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…

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…
