Modeling dark matter halos with self-interacting fermions: A polytropic approach
Fabian Hernandez-Gutierrez, Juan Barranco
In this work we study the possibility of modeling the dark matter content in galaxies as a core-halo model consisting of self-gravitating, self-interacting fermions by means of an…

Extra dip in ultrahigh energy neutrino spectrum from generalized uncertainty principle
J. Barranco, Emiliano Durán
We revisited the scenario of a resonant enhancement in the oscillation probability due to an interaction potential between neutrinos and dark matter with the novelty of the inclusi…

Enhanced extragalactic photon flux by PBH in a stimulated axion/ALP decay scenario
Yadir Garnica, J. Barranco, Luis A. Ureña-López +1
In this work, we show that stimulated decay of axions or axion-like particles in black hole superradiance is an efficient way to find and hunt primordial black holes. When de Brogl…
