Neutron star mergers and the begin of multi-messenger astrophysics — •Stephan Rosswog — The Oskar Klein Centre, Department of Astronomy, Stockholm University

Neutron star mergers had long been suspected to produce gravitational wave "chirps", gamma ray bursts and produce heavy elements via the rapid neutron capture process. While overall convincing, all these conjectures were based on indirect arguments and none was proven directly. This changed on August 17, 2017: a gravitational wave signal from a merging neutron star binary was detected, closely followed by a short gamma-ray burst and week-long transients accross the electromagnetic spectrum coming from the radioactive decay of freshly synthesised r-process elements. In this talk I will give an overview over these recent developments.
