Overview

Explore the fascinating world of primordial black hole dark matter in this comprehensive lecture by Ely D. Kovetz. Delve into indirect detection methods using gravitational waves from primordial black hole binary mergers, examining mass spectra, orbital eccentricity, and spin characteristics. Investigate constraints on the primordial black hole mass fraction and the intriguing "LIGO window." Discover new transient probes like fast radio bursts and their potential for constraining MACHOs through lensing effects. Learn about the observational outlook, timeline, and various ways to probe the primordial black hole dark matter scenario. Gain insights into the connection between primordial black holes and primordial power spectrum limits, as well as their potential role as seeds for supermassive black holes. This lecture, part of the "Less Travelled Path of Dark Matter" program, offers a deep dive into cutting-edge research on alternative dark matter candidates beyond WIMPs.
