Lecture
This lecture covers the formation and gravitational wave signatures of Primordial Black Holes (PBHs), including their role in the early universe, constraints on their abundance, and their potential to explain mass gap events observed by LIGO. The instructor discusses the impact of PBH clustering on merger rates, compares PBH constraints with astrophysical models, and explores future prospects for detecting PBH mergers using 3rd generation detectors.
