ISIS-OG GdR Meeting: Open questions in signal analysis for gravitational astronomy – 8 October 2018

The first observations of advanced LIGO and Virgo mark the advent of a new gravitational astronomy, with great potential for discovery in many fields from fundamental physics to astronomy and cosmology.

This will develop over the next few years as data is taken in the future and in the longer term using new ground-based instruments, such as the Einstein telescope, and in space with the LISA mission.

The scientific production from these observations is based on a range of analytical methods for signal extraction, astrophysical parameter estimation and instrument noise characterization. The objective of this meeting is to bring together the French community working on gravitational astronomy, and that of signal specialists in order to address the signal analysis questions still open in this field.

We will have three tutorial presentations: an introductory presentation and two others on two themes selected for the day. They will be accompanied by presentations and contributed posters.

The two themes considered for the day are:

1. Machine learning
2. Bayesian estimation methods

and their potential applications in gravitational astronomy.

The day will take place on October 8 on the campus of Université Paris Diderot (Paris 13ème, Bibliothèque François Mitterand metro station). Pierre Gilles de Gennes Amphitheatre, level -1 of the Condorcet building of the UFR de Physique, 4 Rue Elsa Morante 75013–

It will begin at 9:30 a.m. and end around 5:00 p.m.
