Avenue de Bourgogne, 17041 La Rochelle, France http://www.seminaire-conference-la-rochelle.org https://goo.gl/maps/c2X8hqd9maRShkCm8 The centre is located at about 5 km from the La Rochelle train station (Gare de La Rochelle) and at about 5 km from the La Rochelle airport (Aéroport de La Rochelle-Ile de Ré). The organization will provide a shuttle transportation from both the train station and the airport to the site in the evening of the first day, and from the site to the train station and the airport in the morning of the last day.

Description

We perform a joint gravitational waves/gamma-ray bursts (GW/GRB) Bayesian analysis in order to put constraints on the low-luminosity end of the short gamma-ray burst (sGRB) population. For this purpose we exploit the results of the modeled search for GW transients associated to short and ambiguous GRBs detected during the O1, O2, O3a and O3b runs of the LIGO/Virgo network and a broken power law to describe the luminosity function of our sGRB population. We use then the results obtained to have an estimate on the rate distribution of the low-luminosity sGRB population and on the joint detection rate between sGRB and GW for the future O4 run.
