SUMMARY:Inferring final state properties from LIGO-Virgo observations of b
 lack-hole and neutron-star binaries - Nathan Johnson-McDaniel\, DAMTP\, LI
 GO-Virgo Collaboration

DESCRIPTION:I will describe how the mass and spin of the final black hole 
 (and radiated energy and peak luminosity) are inferred from LIGO/Virgo obs
 ervations of binary black hole coalescences by applying fitting formulae c
 alibrated to numerical relativity simulations. I will also discuss some of
  the subtleties that need to be understood in order to similarly infer the
  recoil imparted to the final black hole due to the linear momentum radiat
 ed in gravitational waves. Inferring the final state properties for binary
  neutron stars is considerably more complicated\, due to the much richer p
 hysics required to describe them. I will illustrate how one can still comp
 ute the firm lower bound on the radiated energy quoted for GW170817\, as w
 ell as the inferences one can make about the dynamical ejecta and predicti
 ons for the kilonova using only gravitational wave observations and fits t
 o numerical simulations.
