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…
Massive neutrino self-interactions with a light mediator in cosmology
Jorge Venzor, Gabriela Garcia-Arroyo, Abdel Pérez-Lorenzana +1
Nonstandard self-interactions can alter the evolution of cosmological neutrinos, mainly by damping free streaming, which should leave traces in cosmological observables. Although o…
Bounds on neutrino-scalar nonstandard interactions from big bang nucleosynthesis
Jorge Venzor, Abdel Pérez-Lorenzana, Josue De-Santiago
Coherent forward scattering processes by neutrino-scalar nonstandard interactions (SNSI) induce an effective neutrino mass. In the Early Universe, a large neutrino effective mass r…
Constraints on the velocity dispersion of Dark Matter from Cosmology and new bounds on scattering from the Cosmic Dawn
Iván Rodríguez-Montoya, Vladimir Ávila-Reese, Abdel Pérez-Lorenzana +1
The observational value of the velocity dispersion, , is missing in the Dark Matter (DM) puzzle. Non-zero or non-thermal DM velocities can drastically influence Large Sc…
