In this paper, we investigate the properties of binary neutron stars (BNSs) and their mergers by combining population synthesis models for binary stellar evolution (BSE) with cosmological galaxy formation and evolution models. We obtain constraints on BSE model parameters by using the observed Galactic BNSs and local BNS merger rate density (R0) inferred from Gravitational Wave (GW) observations, and consequently estimate the host galaxy distributions of BNS mergers. We find that the Galactic…

Rates of Compact Object Coalescences
Gravitational-wave detections are enabling measurements of the rate of coalescences of binaries composed of two compact objects – neutron stars and/or black holes. The coalescence rate of binaries
