Gravitational Lensing of Core Collapse Supernova Gravitational Wave Signals

Understand

We discuss the prospects of gravitational lensing of gravitational waves (GWs) coming from core-collapse supernovae (CCSN).

• As the CCSN GW signal can only be detected from within our own Galaxy and the local group by current and upcoming ground-based GW detectors, we focus on microlensing.
• We introduce a new technique based on analysis of the power spectrum and association of peaks of the power spectrum with the peaks of the amplification factor to identify lensed signals.
• We validate our method by applying it on the CCSN-like mock signals lensed by a point mass lens.
