Micro Fishing: Whispers of space-time warps and their impact on Long-duration signals

Streszczenie:
The LIGO/Virgo/KAGRA (LVK) collaboration has discovered several dozen binary mergers since 2015; however, binary mergers are not the exclusive sources of gravitational waves. Asymmetric rotating neutron stars and planetary or asteroid mass-primordial BH (PBH) binaries during their in-spiral phase also emit quasi-monochromatic, long-duration gravitational waves. Detecting signals from these sources requires longer observation times due to their low amplitudes relative to detector sensitivities, and thus far, their detection has not been confirmed. Suppose the massive object lies in the line of sight; the signal can undergo gravitational lensing. This presentation provides a brief overview of gravitational wave lensing, an emerging subdomain of gravitational wave astronomy, and the impact of the lensing signature on long-duration signals.
