This study addresses the collapse behavior of neutron star (NS) mergers expressed through the binary threshold mass M_thres for prompt black hole (BH) formation, which we determine by relativistic hydrodynamical simulations for a set of 40 equation of state (EoS) models. M_thres can be well described by various fit formulae involving stellar parameters of nonrotating NSs. Using these relations we compute which constraints on NS radii and the tidal deformability are set by current and future… Expand

Predicting electromagnetic counterparts using low-latency gravitational-wave data products
Searches for gravitational-wave counterparts have been going in earnest since GW170817 and the discovery of AT2017gfo. Since then, the lack of detection of other optical counterparts connected toExpand
