Distinguishing Dressed Black Holes with Gravitational Wave Diffraction

Explore a 35-minute physics lecture that delves into the fascinating world of gravitational wave diffraction and its role in distinguishing dressed black holes from bare black holes. Learn how gravitational lensing patterns in the low-frequency range can reveal the presence of dark matter halos surrounding black holes, potentially providing evidence for primordial black holes. Understand the significance of this detection method for ground-based gravitational wave detectors, particularly for identifying dressed black holes with central masses below 100 solar masses, and its implications for determining the origins of black holes currently detected by LIGO.
