The Chalonge School 18th Paris Cosmology Colloquium 2014

The Chalonge School 18th Paris Cosmology Colloquium 2014 “Latest News from the Universe: LambdaWDM, CMB, Warm Dark Matter, Dark Energy, Neutrinos and Sterile Neutrinos”

The new concordance model in agreement with observations: ΛWDM (Lambda-dark energy- Warm Dark Matter). Recently, Warm (keV scale) Dark Matter emerged impressively over CDM (Cold Dark Matter) as the leading Dark Matter candidate. Astronomical evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored baryonic cures do not work at galactic and small scales is staggering. LambdaWDM solves naturally the problems of LambdaCDM and agrees remarkably well with the observations at galactic and small scales as well as large and cosmological scales. In contrast, LambdaCDM simulations only agree with observations at large scales.

In the context of this new Dark Matter situation, which implies novelties in the astrophysical, cosmological, particle and nuclear physics context, the 18th Paris Colloquium 2014 is devoted to the Latest News from the Universe.

2. This Colloquium is within the astrofundamental physics spirit of the Chalonge School, focalised on recent observational and theoretical progress in the CMB, dark matter, dark energy, the new WDM framework to galaxy formation, and the effective theory of the early universe inflation with predictive power in the context of the LambdaWDM Standard Model of the Universe. The Colloquium addresses as well the theory and experimental search for the WDM particle physics candidates (keV sterile neutrinos). Astrophysical constraints including sterile neutrino decays points the sterile neutrino mass m around 2 keV or nearly larger.

In summary, the aim of the meeting is to put together real data : cosmological, astrophysical, particle, nuclear physics data, and hard theory predictive approach connected to them in the framework of the LambdaWDM Standard Model of the Universe.

Two observed quantities crucially constrain the DM nature in an inescapable way independently of the particle physics model: the average DM density rho and the phase space density Q. The observed values of rho and Q in galaxies today robustly point to a keV scale DM particle (WDM) and exclude CDM as well as axion Bose-Einstein condensate DM.

The fermionic quantum pressure of WDM ensures the observed small scale structures as the cores of galaxies and their right sizes (including the dwarf galaxies). N-body simulations in classical (non-quantum) physics do not take into account the fermionic quantum pressure of WDM and produce unreliable results at small scales: That is the reason of the too small core size problem in classical (non quantum) Nbody WDM simulations and its similar dwarf galaxies problem.

Lyman alpha bounds on the WDM particle mass apply only to specific sterile neutrino models and many sterile neutrino models are available today for which the Lyman alpha bounds are unknown. Therefore, WDM cannot be disfavoured in general on the grounds of the Lyman alpha bounds (only valid or specific models), as erroneously stated and propagated in the literature. Astrophysical constraints put the sterile neutrino mass m in the range 1< m <10 keV. Most of the constraints and last results points to m about 2 keV or nearly larger. MARE, KATRIN, ECHO and PTOLEMY experiments could detect such a keV sterile neutrino. It will be a fantastic discovery to detect dark matter in a beta decay or in electron capture. A exciting WDM work to perform is ahead of us.

The Chalonge School Meudon Workshop 2014 “From large to small scale structures in agreement with observations”

The Chalonge School Meudon Workshop 2014 “From Large to Small scale structures in Agreement with Observations: CMB, WDM, Galaxies, Black holes, Neutrinos and Sterile Neutrinos”

A Turning Point operated recently in the Dark Matter research: Warm Dark Matter (WDM) emerged impressively over Cold Dark Matter (CDM) as the leading Dark Matter candidate. WDM solves naturally the problems of CDM and CDM + baryons.

LambdaWDM provides the same large scale and CMB results than LambdaCDM and agrees with the observations at the galactic and small scales. Warm Dark Matter (WDM) implies progresses in the astrophysical,cosmological, particle and nuclear physics context.

This workshop addresses the last developements in WDM, including its distribution function and equation of state, the quantum mechanical framework to galaxy structure reproducing in particular the observed galaxy cores and their sizes and the dwarf galaxies.

This workshop puts together astrophysical, cosmological, particle and nuclear WDM, astronomical observations, theory and WDM analytical and numerical frameworks which reproduce the observations. The Workshop addresses as well the theoretical and experimental search for the leading WDM particle candidate: keV sterile neutrinos.

The New Dark Matter Situation Today: Warm Dark Matter in Agreement with Observations at all scales: small structures, galaxies, large, cosmological and CMB scales.

The CDM crisis, CDM+ baryons crisis and WIMP crisis and their decline.

Highlights and Conclusions of the Chalonge 16th Paris Cosmology Colloquium 2012

Towards the Chalonge 17th Paris Cosmology Colloquium 2013:
Highlights and Conclusions of the Chalonge 16th Paris Cosmology Colloquium 2012

Summary:

LWDM (Warm Dark Matter) is progressing impressively. The galactic scale crisis and decline of LCDM+baryons (Cold Dark Matter + baryons) are staggering. The 16th Paris Chalonge Colloquium 2012 combined real cosmological/astrophysical/particle/nuclear data and hard theory predictive approach in the LWDM Standard Cosmological Model. News and reviews from ACT, WMAP, SPT, QUIET, Planck, Herschel, JWST, UFFO, KATRIN and MARE experiments; astrophysics, particle and nuclear physics WDM searches, galactic observations, neutrinos, related theory and simulations, with the aim of synthesis and clarification.

Contents:
Highlights by Peter BIERMANN Carlo BURIGANA, Christopher CONSELICE, Asantha COORAY, Hector dE VEGA, Carlo GIUNTI & Marco LAVEDER, John KORMENDI & K FREEMAN, Ernest MA, John MATHER, Lyman PAGE, Norma SANCHEZ, George SMOOT.
Summary and conclusions by dE VEGA, FALVELLA and SANCHEZ.

Data confirm primordial CMB gaussianity. Effective (Ginsburg-Landau) Inflation theory predicts r about 0.04-0.05, negligeable running of ns, the inflation energy scale (GUT scale) and the set of CMB observables in agreement with the data.
WMAP9 and Planck measurements are compatible with one or two Majorana sterile neutrinos in the eV mass scale.

Cored (non cusped) DM halos and keV WDM are strongly favored by theory and observations, Wimps are strongly disfavoured. LambdaCDM + baryons do not work at small scales. Inside galaxy cores, quantum WDM effects are important.
Quantum WDM calculations (Thomas-Fermi) provide galaxy masses, velocity dispersions and cored profiles and their sizes in agreement with observations.

A WDM fermion of about 2 keV naturally reproduces galaxy, large scale and cosmological observations. WDM keV particles deserve dedicated astronomical and laboratory searches, theoretical work and numerical simulations. KATRIN can be adapted to look to keV scale sterile neutrinos. It will be a fantastic discovery to detect dark matter in a beta decay.

Chalonge Meudon Workshop 2013 Warm Dark Matter Galaxies

Chalonge Meudon Workshop 2013 Warm Dark Matter Galaxies in Agreement with Observations: Formation, Evolution and Supermassive Black Holes

SUMMARY: The Workshop addresses the last and fast progresses made in Warm Dark Matter (WDM) Galaxies in agreement with Observations including the new quantum mechanical framework to galaxy structure reproducing in particular the observed galaxy density cores and their sizes.

Warm Dark Matter solves naturally the serious problems of Cold Dark Matter Galaxies, (CDM + baryons), clarifies and simplifies the present galaxy model situation and agrees with the observations at small as well as large and cosmological scales.

This turning point in the galaxy research and the new unifying WDM framework of stars, galaxies and cosmology will be discussed. The Workshop addresses as well the experimental search and astrophysical constraints for the WDM particle candidate keV sterile neutrino.

In the tradition of the Chalonge School, an effort of clarification and synthesis is made by combining in a conceptual framework, predictive theory, analytical, observational and numerical simulation results.

The Meeting is open to all scientists interested in the subject. Advanced students, post-docs, young scientists are encouradged to participate. The format of the Meeting is intended to allow easy and fruitful mutual contact and communication.

Early Registration is strongly encouraged.

The Daniel Chalonge Medal 2012 has been awarded to Professor Brian SCHMIDT

The International Astrophysics School Daniel Chalonge has awarded the Daniel Chalonge Medal 2012 to Professor Brian P. Schmidt, Nobel Laureate of physics 2011 for his outstanding contribution to the discovery of the present accelerated expansion of the Universe, deeply discussed in the framework of the Chalonge School.

Brian Schmidt was lecturer in several courses of the School, and from the very beginning in the discovery of the acceleration of the Universe, which motivated the realization of very important projects in cosmology and the training and formation of young physicists and astrophysicists over the world.

The medal was presented to Brian Schmidt during the Open Session of the 16th Paris Cosmology Colloquium 2012 at the Observatoire de Paris HQ (historic Perrault building) in the Cassini Hall, on the meridian of Paris, which was attended by about hundred participants from the world over, among them four laureates of the Chalonge Medal: John Mather and George Smoot, Nobel laureates of physics, Anthony Lasenby and Peter Biermann.

The Chalonge Medal, coined exclusively for the Chalonge School by the prestigious Hotel de la Monnaie de Paris (the French Mint), is a surprise award and only nine Chalonge medals have been awarded in the 21 year school history.The list of the awarded Chalonge Medals is the following:

1991:Subramanyan Chandrasekhar, Nobel prize of physics. 1992: Bruno Pontecorvo. 2006: George Smoot, Nobel prize of physics. 2007: Carlos Frenk. 2008: Anthony Lasenby. 2008: Bernard Sadoulet. 2009: Peter Biermann. 2011: John Mather, Nobel prize of physics. 2012: Brian Schmidt, Nobel prize of Physics.

With the Chalonge Medal, the International School of Astrophysics Daniel Chalonge confirms its great appreciation to Dr. Brian Schmidt and his huge contribution to the construction of the Standard Model of the Universe, at the center of the Chalonge School programmes. This recognizes the outstanding scientific value and impact of the discovery of the dark energy component, compatible with the cosmological constant, which constitutes about three quarters of the content of the Universe.

ABSTRACT (Abridged)
The Chalonge 15th Paris Cosmology Colloquium 2011 was held on 20-22 July in the historic Paris Observatory’s Perrault building, in the Chalonge School spirit combining real cosmological/astrophysical data and hard theory predictive approach connected to them in the Warm Dark Matter Standard Model of the Universe: News and reviews from Herschel, QUIET, Atacama Cosmology Telescope (ACT), South Pole Telescole (SPT), Planck, PIXIE, the JWST, UFFO, KATRIN and MARE experiments; astrophysics, particle and nuclear physics warm dark matter (DM) searches and galactic observations, related theory and simulations, with the aim of synthesis, progress and clarification.
Philippe Andre, Peter Biermann, Pasquale Blasi, Daniel Boyanovsky, Carlo Burigana, Hector de Vega, Joanna Dunkley, Gerry Gilmore, Alexander Kashlinsky, Alan Kogut, Anthony Lasenby, John Mather, Norma Sanchez, Alexei Smirnov, Sylvaine Turck-Chieze present here their highlights of the Colloquium. Ayuki Kamada and Sinziana Paduroiu present here their poster highlights.

LambdaWDM (Warm Dark Matter) is progressing impressively over LambdaCDM whose galactic scale crisis and decline are staggering. The International School Daniel Chalonge issued an statement of strong support to the James Webb Space Telescope (JSWT). The Daniel Chalonge Medal 2011 was awarded to John C. Mather, Science PI of the JWST. Summary and conclusions are presented by H. J. de Vega, M. C. Falvella and N. G. Sanchez.

Overall, LambdaWDM and keV scale DM particles deserve dedicated astronomical and laboratory experimental searches, theoretical work and simulations. KATRIN experiment in the future could perhaps adapt its set-up to look to keV scale sterile neutrinos. It will be a a fantastic discovery to detect dark matter in a beta decay. Photos of the Colloquium are included. (Abridged)

16th Paris Cosmology Colloquium "The New Standard Model of the Universe: Lambda Warm Dark Matter. Theory and Observations"

Ecole Internationale d’Astrophysique Daniel Chalonge

Chalonge School 16th Paris Cosmology Colloquium 2012 “The New Standard Model of the Universe: Lambda Warm Dark Matter. Theory and Observations”

1. SUMMARY
Recently, Warm (keV scale) Dark Matter emerged impressively over CDM (Cold Dark Matter) as the leading Dark Matter candidate. Astronomical evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored cures do not work at small scales is staggering. LambdaWDM solves naturally the problems of LambdaCDM and agrees remarkably well with the observations at small as well as large and cosmological scales. LambdaWDM numerical simulations naturally agree with observations at all scales, in contrast to LambdaCDM simulations which only agree at large scales. In the context of this new Dark Matter situation, which implies novelties in the astrophysical, cosmological and keV particle physics context, this 16th Paris Colloquium 2012 is devoted to the LambdaWDM Standard Model of the Universe. In summary, the aim of the meeting is to put together real data: cosmological, astrophysical, particle, nuclear physics data, and hard theory predictive approach connected to them in the framework of the Lambda WDM Standard Model of the Universe.

2. THIS COLLOQUIUM
This Colloquium is within the astrofundamental physics spirit of the Chalonge School, focalised on recent observational and theoretical progress in the CMB, dark matter, dark energy, structure formation, and the theory of the early universe inflation with predictive power in the context of the LambdaWDM Standard Model of the Universe. The Colloquium addresses as well the theory and experimental search for the WDM particle physics candidates (keV sterile neutrinos). Astrophysical constraints including Lyman alpha bounds put the sterile neutrino mass m in the range 1< m < 13 keV. WDM predictions for EUCLID and PLANCK start to to be available. MARE and an adapted KATRIN experiment could detect a keV sterile neutrino. It will be a fantastic discovery to detect dark matter in a beta decay. A formidable WDM work to perform is ahead of us.

3. TOPICS
Observational and theoretical progress on the nature of dark matter: keV scale warm dark matter. Cored density profiles in agreement with observations. Large and small scale structure formation in agreement with observations at large scales and small (galactic) scales. Warm (keV scale) dark matter from theory and observations. Warm (keV scale) dark matter N-body simulations in agreement with observations. Neutrinos in astrophysics and cosmology. The new serious dark matter candidate: Sterile neutrinos at the keV scale.Neutrinos mass bounds from cosmological data and from high precision beta decay experiments. Dark energy: cosmological constant: the quantum energy of the cosmological vacuum. The analysis of the CMB+LSS+SN data with the effective (Ginsburg-Landau) effective theory of inflation: New Inflation (double well inflaton potential) strongly favored by the CMB + LSS + SN data. The presence of the lower bound for the primordial gravitons (non vanishing tensor to scalar ratio r) with the present CMB+LSS+SN data. CMB news and polarization. Forecasts and Planck results, and Other Topics.

FORMAT and EXHIBITION
Sessions last for three days in the beautiful Parisian campus of Observatoire de Paris (built on orders from Colbert and to plans by Claude Perrault from 1667 to 1672). All sessions take place at the Salle Cassini (Cassini Hall) in the historic Perrault building (“Bâtiment Perrault”) of Observatoire de Paris HQ, just upstairs “Salle du Conseil” (Council Room).

Chalonge School Meudon Workshop 2012 "Warm Dark Matter Galaxy Formation in Agreement with Observations"

Ecole Internationale d’Astrophysique Daniel Chalonge

1. Summary: A Turning Point operated recently in the Dark Matter research: Warm Dark Matter (WDM) emerged impressively over Cold Dark Matter (CDM) as the leading Dark Matter candidate. WDM solves naturally the problems of CDM and agrees with the observations at small as well as large and cosmological scales. This workshop addresses WDM putting together astrophysical, cosmological and particle WDM, astronominal observations, theory and WDM numerical simulations which naturally reproduce the observations at all the scales. The Workshop addresses as well the experimental search for the WDM particle candidates (keV sterile neutrinos).

2. The New Dark Matter Situation Today: Warm Dark Matter (WDM) research is progressing fast, the subject is new and WDM essentially works, naturally reproducing the astronomical observations over all scales: small (galactic) and large (cosmological) scales (LambdaWDM). Astronomical evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored cures do not work at small scales is staggering. Astrophysical constraints including Lyman alpha bounds put the sterile neutrino mass m in the range 1< m <13 keV. WDM predictions for EUCLID and PLANCK start to to be available. MARE and an adapted KATRIN experiment could detect a keV sterile neutrino. It will be a fantastic discovery to detect dark matter in a beta decay. A formidable WDM work to perform is ahead of us.

3. History, Context and the CDM crisis (abridged): This Workshop is the third of a new Chalonge series in Meudon dedicated to Dark Matter. The first Workshop of this series (June 2010) allowed to identify and understand the issues of the serious problems faced by Cold Dark Matter (CDM) to reproduce the galactic (and even cluster of galaxies) observations. The 2010 and 2011 Workshops served as well to verify and better understand the confusion in the CDM research, namely the increasing number of cyclic arguments, and ad-hoc mechanisms introduced in the CDM simulations over most of twenty years, in trying to deal with the CDM small scale crisis: Cusped profiles and overabundance of substructures are predicted by CDM. Too many satellites are predicted by CDM simulations while cored profiles and no such overabundant substructures are seen by astronomical observations. Read more on the www of this Workshop.

4. The Workshop addresses the last progresses made in Warm Dark Matter and the Universal and Non Universal properties of Galaxies. In the tradition of the Chalonge School, an effort of clarification and synthesis will be made by combining in a conceptual framework, theory, analytical, observational and numerical simulation results that reproduce observations.

The subject will be approached in a threefold way:
(I) Conceptual context and keV WDM particle candidates, sterle neutrinos
(II) Astronomical observations linked to the galaxy structural properties, surveys, clusters and to structure formation at different (large and small (galactic) scales).
(III) WDM Numerical simulations which reproduce observations at large and small (galactic) scales.

TOPICS:
Recent progress in solving the Boltzmann-Vlasov equation to obtain the observed properties of galaxies (and clusters of galaxies). N-body numerical simulations with Warm Dark Matter. The surface density. The phase-space density. Particle model independent analysis of astrophysical dark matter. The impact of the mass of the dark matter particle on the small scale structure formation. The radial profiles and the Dark Matter distribution. Cored DM observed profiles. The keV scale Dark Matter (Warm Dark Matter): Observational and theoretical progresses. Large and small scale structure formation in agreement with observations at large and small (galactic) scales. The new serious dark matter candidate: Sterile neutrinos at the keV scale.

Sessions last for three full days in the beautiful green Meudon campus of Observatoire de Paris, where CIAS "Centre International d´Ateliers Scientifiques" is located. All sessions take place in the historic Château building, (built in 1706 by great architect Jules-Hardouin Mansart in orders by King Louis XIV for his son the Grand Dauphin).

The Meeting is open to all scientists interested in the subject. The format of the Meeting is intended to allow easy and fruitful mutual contact and communication.

ABSTRACT (Abridged):

Warm Dark Matter (WDM) research is progressing fast, the subject is new and WDM essentially works, naturally reproducing the astronomical observations over all scales: small (galactic) and large (cosmological) scales (LambdaWDM). Evidence that Cold Dark Matter (LambdaCDM) and its proposed tailored cures do not work at small scales is staggering.

Fedor Bezrukov, Pier-Stefano Corasaniti, Hector J. de Vega, Stefano Ettori, Frederic Hessmann, Ayuki Kamada, Marco Lombardi, Alexander Merle, Christian Moni Bidin, Angelo Nucciotti on behalf of the MARE collaboration, Sinziana Paduroiu, Henri Plana, Norma Sanchez, Patrick Valageas, Shun Zhou present here their highlights of the Workshop. LambdaWDM simulations with keV particles remarkably reproduce the observations, small and large structures and velocity functions. Cored DM halos and WDM are clearly determined from theory and astronomical observations, they naturally produce the observed structures at all scales. keV sterile neutrinos are the leading candidates, they naturally appear extensions of the standard model of particle physics. Astrophysical constraints including Lyman alpha bounds put its mass in the range 1< m <13 keV. Predictions for EUCLID and PLANCK have been presented. MARE and an adapted KATRIN experiment could detect a keV sterile neutrino. It will be a fantastic discovery to detect dark matter in a beta decay. A formidable WDM work to perform is ahead of us, these highlights point out some relevant research directions to put the effort. Photos of the Workshop are included.

We thank all again, both lecturers and participants, for having contributed so much to this Workshop and look forward to seeing you again in a next Meeting of this series.

The 14th Paris Cosmology Colloquium Chalonge 2010
“The Standard Model of the Universe: Theory and Observations”

Greetings from Paris. We are pleased to inform you that the Highlights and Conclusions of the Chalonge 14th Paris Cosmology Colloquium 2010 (54 pages, 19 figures) have appeared as http://arxiv.org/abs/1009.3494 and are also available (.ps printing format) on the web site of the Colloquium:

———————————————————————–

Abstract (Abridged)

The Chalonge 14th Paris Cosmology Colloquium was held on 22-24 July 2010 in Paris Observatory on the Standard Model of the Universe: News from WMAP7, BICEP, QUAD, SPT, AMI, ACT, Planck, QUIJOTE and Herschel; dark matter (DM) searches and galactic observations; related theory and simulations; aiming synthesis, progress and clarification. P. Biermann, D. Boyanovsky, A. Cooray, C. Destri, H. de Vega, G. Gilmore, S. Gottlober, E. Komatsu, S. McGaugh, A. Lasenby, R. Rebolo, P. Salucci, N. Sanchez and A. Tikhonov present here their highlights of the Colloquium. Inflection points emerged: LambdaWDM (Warm DM) emerges impressively over LambdaCDM whose galactic scale problems are ever-increasing.

Summary and conclusions by H. J. de Vega, M. C. Falvella and N. G. Sanchez stress among other points: (i) Primordial CMB  gaussianity is confirmed. Inflation effective theory predicts a tensor to scalar ratio 0.05-0.04 at reach/border line of next CMB observations, early fast-roll inflation provides lowest multipoles depression. SZ amplitudes are smaller than expected: CMB and X-ray data agree but intracluster models need revision and relaxed/non-relaxed clusters distinction. (ii) cosmic ray positron excess is explained naturally by astrophysical processes, annihilating/decaying dark matter needs growing tailoring. (iii) Cored (non cusped) DM halos and warm (keV scale mass) DM are increasingly favored from theory and observations, naturally producing observed small scale structures, wimps turn strongly disfavoured. LambdaWDM 1 keV simulations well reproduce observations. Evidence that LambdaCDM does not work at small scales is staggering. P Biermann presents his live minutes of the Colloquium and concludes that a keV sterile neutrino is the most interesting DM candidate.

Photos of the Colloquium are included.

Abstract:

The Workshop approached DM in a fourfold way: astronomical observations of DM structures (galaxy properties, halos, rotation curves and density profiles), DM numerical simulations (with and without baryons), theoretical astrophysics and cosmology (kinetic theory, Boltzmann-Vlasov evolution), astroparticle physics. Peter Biermann, Alfonso Cavaliere, Hector J. de Vega, Gianfranco Gentile, Chandra Jog, Andrea Lapi, Paolo Salucci, Norma G. Sanchez, Pasquale Serpico, Rainer Stiele, Janine van Eymeren and Markus Weber present here their highlights of the Workshop.

The summary and conclusions by H. J. de Vega and N. G. Sanchez stress among other points the growing evidence that DM particles have a mass in the keV scale and that those keV scale particles naturally produce the small scale structures observed in galaxies. Wimps (DM particles heavier than 1 GeV) are strongly disfavoured combining theory with galaxy astronomical observations.

Peter Biermann presents his live minutes of the Workshop and concludes that a right-handed sterile neutrino of mass of a few keV is the most interesting DM candidate. Photos of the Workshop are included.
