Mock Catalogs of Strongly Lensed Gravitational Waves via a Halo Model Approach with Space-borne Detectors
This work developed a framework to simulate strongly lensed gravitational waves for LISA and DECIGO using realistic astrophysical models. It constructed mock catalogs based on halo mass functions and density profiles, showing expected event rates ranging from 0 to 131 for LISA and around 0.15% lensing probability for DECIGO sources. The study emphasizes that signal overlap due to lensing time delays significantly impacts signal-to-noise ratio estimation.
