GW170817 and its EM counterparts - The dawn of multi-messenger astronomy

Séminaire IPAG de Amir Levinson (Tel Aviv University & IPAG), jeudi 11 janvier 2018 à 11h00, salle Manuel Forestini IPAG

The detection of multi-messenger emissions from the gravitational wave source GW170817 has lent strong support to the hypothesis that neutron star mergers are the progenitors of short GRBs, and that these events constitute the primary source of r-process elements in the Universe. While the various data confirms earlier predictions by and large, it also revealed a small surprise. In this talk I will describe the main observations and their theoretical interpretation, as perceived in the recent literature.
