Effects of Galaxy Cluster Structure on Lensed Gravitational Waves

Understand

Strong gravitational lenses come in many forms, but are typically divided into two populations: galaxies, and groups and clusters of galaxies.

• The largest objects in the Universe (i.e.
• galaxy clusters) are highly irregular and composed of many components due to a history of (or active) hierarchical mergers.
• In this work, we analyze the discrepancies in the observables of strongly lensed gravitational wave transients in both scenarios, namely relative magnifications, time delays, and image multiplicities.
