Future GW detector networks and EM observatories will provide a unique
opportunity to observe the most luminous events in the Universe involving
matter in extreme environs. They will address some of the key questions in
physics and astronomy: formation and evolution of compact binaries, sites of
formation of heavy elements and the physics of jets.Comment: 11 pages, two tables, White Paper submitted to the Astro-2020 (2020
