DESCRIPTION:In the past three years\, the LIGO and Virgo gravitational wav
 e\n(GW) detectors have announced the discovery of ten binary black hole me
 rgers\nas well as the the first binary neutron star merger GW170817. The d
 iscovery\nof both gravitational wave and electromagnetic (EM) radiation 
 from this\nbinary neutron star merger\, GW170817\, has opened up a new er
 a of\nmulti-messenger GW+EM astronomy. The EM follow-up campaign for this 
 single\nevent was unprecedented in terms of its scale\, coordination\nand
  the resulting observational data-sets. Although only a single event\, t
 he\nfollow-up and joint GW+EM characterization have offered us a new persp
 ective\non the Universe enabling critical insights into diverse fields fr
 om gravity\,\nhigh-energy astrophysics\, nuclear physics\, to cosmology. I
 n this talk\, I\nwill give a brief overview of the GW discovery and EM fol
 low-up of this\nevent\, and then discuss how to place compact object merg
 ers in their full\nastrophysical and cosmological context using joint GW+E
 M measurements. I\nwill conclude by discussing the lessons that we are le
 arning from this one\nevent and the remarkable opportunities and challenge
 s that have emerged in\nthis new observationally-driven and fast-paced fie
 ld as we move from the\ndiscovery era to one of precision astrophysics in 
 the next decade.\n
