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, […]

Gamma-ray bursts and supernovae: from the central engines to the observer

  A four-week scientific program on extreme explosive events (such as gamma-ray bursts, compact object mergers, core-collapse supernovae) is held at Institut d’Astrophysique Spatiale and sponsored by the Ψ2 initiative of the Paris-Saclay University. In this program we aim to bring together and foster interactions between several communities (core collapse supernovae, gamma-ray bursts, neutron star mergers and magnetars). For this […]

Advanced Virgo + Day on May 31, 2018

A French Advanced Virgo + day is organized on May 31 in Paris (ENS, 24 rue Lhomond). It will be an opportunity to present the instrumental evolutions envisaged for Advanced Virgo, as well as the science that will then be accessible and the evolution of the data analysis that will be necessary. This day is open to all those who […]
