We study the detectability of next-generation gravitational wave detectors by analyzing 10 post-merger signals in binary neutron star simulations assuming they are sources located at d = 88 Mpc and d = 159 Mpc. The simulation characteristics are based on the binary parameters estimated for the GW190425 event. Our results show that the most optimistic result is given by the Cosmic Explorer detector at the highest values of the merger rate (R0 = 1700 Gpc−3yr−1) and signal-to-noise ratio (SNRhigh = 5.34 ± 3.06), providing N = 1.44 ± 2.48 detections per year.
Keywords: binary neutron star coalescences, BNS merger rate, next-generation detectors, number of detections, post-merger phase gravitational waves
