Hawking emission of massive vector fields by Kerr black holes
Marco CalzÃ, Miguel Faria, Yuber F. Perez-Gonzalez +1
We compute, for the first time, the Hawking emission spectrum of massive vector (Proca) fields by spinning Kerr black holes, determining the associated greybody factors and the res…
: Hawking Radiation from Regular Black Holes
Alexandre Arbey, Marco CalzÃ, Léa Malacher +2
We present , a major update of the public code designed to compute Hawking radiation spectra of black holes. Building upon previous versions, this release…
Bose-enhanced Neutrino Decays in a Thermal Medium
Yuber F. Perez-Gonzalez, Manibrata Sen, Walter Tangarife
We compute the decay width of neutrinos in a thermal medium using finite-temperature quantum field theory, focusing on non-standard decays into lighter neutrinos and a scalar or li…
Dynamic Neutrino Mass Ordering and Its Imprint on the Diffuse Supernova Neutrino Background
Yuber F. Perez-Gonzalez, Manibrata Sen
Neutrino masses may have evolved dynamically throughout the history of the Universe, potentially leading to a mass spectrum distinct from the normal or inverted ordering observed t…
ULYSSES the Third: An Odyssey Towards a Unified Python Toolkit for Leptogenesis
Alessandro Granelli, Juraj KlariÄ, Dhruv Pasari +2
We present the third release of , a Python package for the numerical evaluation of the baryon asymmetry generated through leptogenesis. This version includes code…
Multi-messenger Constraints on a Primordial Black Hole Origin of the KM3-230213A Event
Yuber F. Perez-Gonzalez
Black holes are expected to end their lifetime in a burst of Hawking radiation, emitting all Standard Model particles at ultra-high energies. The evaporation of a nearby primordial…
