Primordial Black Holes and Gravitational Waves Special issue

Primordial Black Holes (PBHs) and Gravitational Waves (GWs) represent key topics at the intersection of cosmology, astrophysics and particle physics. PBHs, thought to arise from density fluctuations in the early Universe, offer valuable insights into dark matter and cosmic evolution. GWs, which are generated not only by accelerating masses such as merging black holes but also from various phenomena throughout the evolution of the Universe, provide a new observational window into the Universe. This special issue aims to explore the theoretical foundations, observational strategies, and experimental approaches related to PBHs and GWs, bridging the gap between predictions and data. We will cover PBH formation mechanisms, mass spectrum, and distribution, their role as GW sources, and constraints and detection methods for GWs. This issue invites contributions that advance our understanding through a synergy of theoretical models and cutting-edge observational techniques, promoting interdisciplinary research to elucidate the early Universe and the nature of dark matter.
