SUMMARY:Inferring neutron star properties with gravitational waves from bi
 nary mergers - Michalis Agathos (University of Cambridge)

DESCRIPTION:The first detection of a gravitational-wave (GW) signal from a
  binary neutron star coalescence\, known as GW170817\, by the LIGO and Vir
 go observatories\, signified the beginning of a new era in astrophysics. B
 y analysing GW signals from neutron star binaries\, using adequate modelli
 ng of matter effects\, we have constrained the barotropic equation of stat
 e (EoS) of cold matter at supranuclear densities found in the neutron-star
  interior. Recently\, a second such event was detected\, GW190425. In this
  talk I will describe how the analysis on GW data put constraints on the s
 tars' tidal parameters\, radii and EoS and will focus on how we can infer 
 the nature of the final remnants based on GW data alone. I will briefly di
 scuss the prospects of extracting additional information by using observat
 ions of EM counterparts and by modelling and analysing the post-merger par
 t of the gravitational waveform.
