Baryogenesis via Asymmetric Evaporation of Primordial Black Holes
Joaquim Iguaz Juan, Yuber F. Perez-Gonzalez, Jessica Turner
We revisit baryogenesis from the asymmetric evaporation of light primordial black holes, focusing on scenarios where gravitational effects induce a matter antimatter asymmetry. In…
Could a Primordial Black Hole Explosion Explain the extremely high-energy KM3NeT neutrino Event?
Lua F. T. Airoldi, Gustavo F. S. Alves, Yuber F. Perez-Gonzalez +2
A black hole is expected to end its lifetime in a cataclysmic runaway burst of Hawking radiation, emitting all Standard Model particles with ultra-high energies. Thus, the explosio…
Chasing Serendipity: Tackling Transient Sources with Neutrino Telescopes
Lua F. T. Airoldi, Gustavo F. S. Alves, Yuber F. Perez-Gonzalez +2
The discovery of ultra-high-energy neutrinos by IceCube marked the beginning of neutrino astronomy. Yet, the origin and production mechanisms of these neutrinos remain an open ques…
Gray-body factors: Method matters
Alexandre Arbey, Marco Calzà, Yuber F. Perez-Gonzalez
The calculation of gray-body factors is essential for understanding Hawking radiation and black hole thermodynamics. While the formalism developed by Chandrasekhar is effective for…
Neutrino Emission and Plasma Heating from Primordial Black Holes: An Improved Approach to Constraints
Héctor Sanchis, Gabriela Barenboim, Yuber F. Perez-Gonzalez
We investigate the impact of neutrino emission via Hawking radiation from primordial black holes (PBHs) on the cosmological effective number of neutrino species, …
Page Time of Primordial Black Holes in the Standard Model and Beyond
Yuber F. Perez-Gonzalez
The Page time marks the moment when the von Neumann entropy of the emitted Hawking radiation equals the Bekenstein-Hawking entropy of an evaporating black hole, which is assumed to…
