Event rate predictions of strongly lensed gravitational waves with detector networks and more realistic templates

Understand

Strong lensing of gravitational waves (GWs) is attracting growing attention of the community.

• The event rates of lensed GWs by galaxies were predicted in numerous papers, which used some approximations to evaluate the GW strains detectable by a single detector.
• The joint-detection of GW signals by a network of instruments will increase the detecting ability of fainter and farther GW signals, which could increase the detection rate of the lensed GWs, especially for the 3rd generation detectors, e.g., Einstein Telescope (ET) and Cosmic Explorer (CE).
• Moreover, realistic GW templates will improve the accuracy of the prediction.
