Abstract

Pulsar binaries are important targets for ground-based and future space-borne gravitational-wave (GW) detectors. In order for improving detector design and assessing detector performances, it is a prerequisite to understand the astrophysics of GW sources such as the population size or merger rates. Here, we summarize recent results for Galactic merger rates of two known types of pulsar binaries: (a) double-neutron star-system (DNS) and (b) neutron star-white dwarf (NS-WD) binaries. Based on the merger rate estimates, we discuss prospects for the ground-based interferometers considering LIGO (Laser Interferometer Gravitational-wave Observatory) and space mission LISA (Laser Interferometer Space Antenna).
