Towards a complete scheme of cosmological neutrino self-interactions: Collision term for a wide range of mediator masses
Ivan Pérez-Castro, Josue De-Santiago, Gabriela Garcia-Arroyo +2
Neutrino self-interactions (NSI) offer a potential pathway to address anomalies in standard cosmology and explain existing cosmological tensions. In this work, we present a novel f…

Resonant neutrino self-interactions: Insights from the full shape galaxy power spectrum
Hernán E. Noriega, Josue De-Santiago, Gabriela Garcia-Arroyo +2
This paper investigates resonant neutrino self-interactions in cosmology by employing, for the first time, the effective field theory of large-scale structure to model their impact…

Resonant neutrino self-interactions and the tension
Jorge Venzor, Gabriela Garcia-Arroyo, Josue De-Santiago +1
In this work, we study the previously unexplored resonant region of neutrino self-interactions. Current disagreement on late and early time observations of the Universe expansion c…
