The LISA Symposium is an open conference which is dedicated to the science and technology of space-based gravitational wave detectors targeting the 10uHz to 1Hz frequency range.
The 10th International LISA Symposium will be held at the Hilton Conference Center in Gainesville from May 18-23, 2014. The registration website will open December 2013.

The 9th LISA Symposium (2012) will take place at BnF – Paris (National Library of France close to APC Laboratory) on 21 – 25 May 2012.
Main topics: LISA, eLISA-NGO, future of space based gravitational wave astronomy, gravitational waves, astrophysics, cosmology
The earlier registration deadline is the 20 April 2012.
Due to the recent adjustment in how L-class missions within the Cosmic Vision framework are chosen, ESA is currently investigating a design for a European-led variant of LISA that can be launched before 2022.
After studying several configurations, a new baseline has been identified that will be refined in the coming month with the help of European industry. The new baseline simplifies the design of LISA, reducing the distance between the satellites and employing only four instead of previously six laser links.
The science team and a science task force, composed of members of the gravitational wave and astrophysics communities in both Europe and the US, have assessed the scientific validity of the new baseline for the fields of physics, astrophysics and cosmology and have shown that the new configuration is very promising regarding sources such as galactic binaries, (super)massive black hole and extreme mass ratio inspirals.
Over the next few months, this work will continue until we have a finalised mission proposal by the fall of 2011. The near future is very bright for astrophysics and cosmology using observations of gravitational waves in space.

We are glad to announce the 6th (!) Astro-GR meeting. This time we will meeting from Monday 5th to Friday September 9th 2011 in Palma de Mallorca to discuss about astrophysics and gravitational waves, focusing on the science the new European envisioned and other future missions can do, such as:
* Astrophysical modelling of super- and massive black hole coalescences
* Astrophysical modelling of small compact objects by massive black holes (aka “EMRIs”)
* Observations of our own Galactic Center (SgrA*)
* Observations of binary neutron stars leading up to coalescence for long periods of time
* Precision astronomy of massive stellar bodies and measurements of spin-down of individual pulsars
* Modelling of strong field sources within General Relativity
* Data analysis of the sources
* Early warning of possible mergers either from the data analysis or by EM detection
* Coincidence measurements with ground-based GW detectors
This meeting will be run in the style of all previous Astro-GR meetings, with presentations in the morning and discussion/working groups in the afternoon. This format has worked very well in the past, so we have decided to use it again for this meeting. The format and venue for Astro-GR@Mallorca will limit the number of attendees. We thus kindly ask every participant to register as soon as s/he makes travel arrangements and to avoid disappointment. In keeping with the spirit of an informal workshop, there will be no registration fee. The number of slots will be very limited, and they will be chosen by the organizers on the basis of their relevance to the main focus and goal of this meeting. Please take a look to this link to get an impression of the general philosophy of the meetings: http://www.aei.mpg.de/~pau/astro_gr.html
A key aim of the Astro-GR meetings is to foster and develop new collaborative ventures, as well as to strengthen existing ones, within the different communities (astrophysics, data analysis, general relativity and numerical relativity). Looking forward to getting your registrations!

The Mock LISA Data Challenges (MLDCs) are a program to demonstrate LISA data-analysis capabilities and to encourage their development. Each round of challenges consists of one or more datasets containing simulated instrument noise and gravitational waves from sources of undisclosed parameters. Participants analyze the datasets and report best-fit solutions for the source parameters. Almost four years after the program began, we are proud to announce the release of the fourth challenge, MLDC 4. To obtain the datasets, go to http://astrogravs.nasa.gov/docs/mldc and follow the “Round 4″ link. The authoritative description of MLDC 4 will appear in the Amaldi-8 proceedings; in the meantime please refer to http://lisatools.googlecode.com/svn/Docs/2009-amaldi-challenge3/mldc3proceedings.pdf .
Challenge content — While the third round of the MLDCs was focused on increasing the complexity and variety of GW sources, we are devoting the next iteration to the global-fit problem of detecting and analyzing sources of different types superposed in the LISA data. Thus, MDLC 4 consists of a single, “whole enchilada” challenge that includes all the sources of MLDCs 3.1-3.5 in the same dataset, albeit with larger source numbers (for EMRIs and cosmic-string bursts) and parameter ranges (for MBH binaries and EMRIs). You can find a graphic representation of a typical dataset at http://www.tapir.caltech.edu/dokuwiki/_media/listwg1b:mldc4.pdf ;
this particular realization includes 60+ million chirping Galactic binaries, 4 MBH binaries, 9 EMRIs, 15 cosmic-string bursts, an isotropic stochastic background, and of course instrument noise (the graphic reflects a previous test run that is not available for download).
Participating — The deadline for Round 4 entries will be December 3, 2010, at midnight, U.S. Pacific time, with preliminary results to be presented at the 15th GWDAW meeting. (However: the GWDAW-15 date and place will be decided in Jan 2010; if GWDAW-15 is in early December 2010, we will bring forward the MLDC 4 deadline accordingly to have enough time to evaluate entries.) The global-fit character of this challenge encourages collaborative endeavors between group that have developed searches for different sources. We invite you to use the firstname.lastname@example.org list as a forum to set up such collaborations (subscribe at http://www.gravity.psu.edu/mailman/listinfo/lisatools-challenge); please let us know how we may help you on this.
