Primordial black hole neutrinogenesis of sterile neutrino dark matter
Sterile neutrinos are well-motivated and actively searched for new particles that would mix with the active neutrinos. We study their phenomenology when they are produced in the evaporation of early Universe black holes, a novel production mechanism that

Magnetic monopole meets primordial black hole: an extended analysis
We investigate gravitational capture of magnetic monopoles by primordial black holes (PBH) that evaporate before Big Bang Nucleosynthesis (BBN), a hypothetical process which was once proposed as an alternative solution to the monopole problem.

Primordial black hole-driven cosmic acceleration
In this paper, we propose a natural mechanism for cosmic acceleration driven by Primordial Black Holes (PBHs) with repulsive behavior, within a Swiss Cheese cosmological framework. Considering regular black hole spacetimes such as Hayward, Bardeen and Dymnikova as well as the singular Schwarzschild-de Sitter case we consistently find a robust PBH ...

Gravitational Waves from Primordial Black Hole Dark Matter Spikes
The origin of the binary black hole mergers observed by LIGO–Virgo–KAGRA remains an open question. We calculate the merger rate from primordial black holes (PBHs) within the density spike around supermassive black holes (SMBHs) at the centers of galaxies.
