WebApr 13, 2024 · Primordial black holes are a hypothetical type of black hole that formed soon after the Big Bang. It is believed that they are formed as a result of collapsing radiations as opposed to the collapse of massive stars, which is the case of any other black holes. The recent study has confirmed that this marginal rise in potential energy resulted in ... WebOct 13, 2024 · Primordial Black Holes (PBH) can form in the early universe and might comprise a significant fraction of the dark matter. Interestingly, they are accompanied by the generation of Gravitational Wave (GW) signals and they could contribute to the merger events currently observed by the LIGO/Virgo Collaboration (LVC). In this thesis, we study …
