Gravitational Lensing of Gravitational Waves： detection and applications to multi messenger astronomy and cosmology

量子物理学・ナノサイエンス第92回特別セミナー

概要

Gravitational lensing of gravitational waves (GWs) occurs when these GWs encounter large agglomerations of matter, resulting in the production of (resolvable or unresolvable) images. This is a highly anticipated phenomenon expected to be detected in future observing runs of the LIGO-Virgo-Kagra detector network. In this seminar, I will give a brief overview of a few of my works pertaining to this topic. Specifically, I will talk about the data analysis techniques used to detect strongly lensed GWs and how the non-detection of microlensed GWs can enable constraints on the fraction of dark matter as massive compact halo objects. I will additionally look into the future to see if GW lensing can be leveraged as a tool for GW early warning, for identification of compact binary coalescences as progenitors of FRBs, and constraining cosmological parameters.
