We revisit the lower bound on binary tidal deformability (Lambda) over tilde imposed by a luminous kilonova/macronova, AT 2017gfo, by numerical-relativity simulations of models that are consistent with gravitational waves from the binary neutron s...

We identify various contributors of systematic effects in the measurement of the neutron star (NS) tidal deformability and quantify their magnitude for several types of neutron star-black hole (NSBH) binaries. Gravitational waves from NSBH mergers...
The location of the cutoff in the gravitational-wave spectrum of black
hole-neutron star mergers is correlated strongly with the neutron-star radius
for the case that the neutron star is disrupted by the black hole during the
merger. However, the ...
