Multi-messenger insights into merger physics: GW170817 and beyond |
|
Abstract |
With the first gravitational wave detection on September 2015 and the forthcoming new developments of gravitational interferometers, neutrino detectors, as well as ground- and space-based telescopes, a golden era of multi-messenger astronomy is approaching. Multi-messenger observations enable us to obtain a more complete phenomenological picture of several astrophysical phenomena. The most beautiful example so far is represented by the binary neutron star merger detected on August 17th, 2017 by the gravitational wave detector network (formed by Advanced LIGO and Advanced Virgo) and by several telescopes covering the whole electromagnetic spectrum. Multi-messenger observations of this source have enabled us to make huge steps forward in our knowledge of merging neutron star binary systems and their connection with short gamma-ray bursts and with the Universe chemical enrichment of heavy elements. Many other open questions will be tackled in the next years given the realistic possibility to obtain multi-messenger observations for a large number of such systems with the present and future instrumentations. In this talk I will summarize some of the main results obtained for GW170817 and the future perspectives for multi-messenger astronomy. |
