Multimessenger astrophysics in the era of gravitational waves: first results and perspectives.
Razzano M. per la Collaborazione LIGO Scientific e per la Collaborazione Virgo
The direct detection of gravitational waves from the coalescence of binary black holes marked the birth of gravitational wave astronomy and opened a new chapter in the multimessenger study of the cosmos. Among gravitational wave sources, mergers of compact objects containing at least one neutron star are thought to be associated with electromagnetic transient phenomena ($e.g.$ short Gamma Ray Bursts). Simultaneous observations of gravitational interferometers and ground-based or space telescopes will thus provide an unique opportunity to find the electromagnetic counterparts of these gravitational wave sources. The talk will discuss the results on the follow-up campaigns of gravitational wave transients, and highlight the perspectives and challenges for multimessenger observations.
