Dark energy from neutrino interactions in Unimodular Gravity
Alejandro Gil-Ocaranza, Josue De-Santiago, Mauricio Lopez-Hernandez +1
We investigate a dark energy scenario generated by neutrino interactions mediated by a light scalar field, in which finite-temperature corrections induce an effective neutrino mass…
Comparing Hemispheres: Anisotropy in the deceleration parameter
Mauricio Lopez-Hernandez, Josue De-Santiago
We present a hemispherical comparison analysis of the deceleration parameter using the Pantheon+ sample of Type Ia supernovae to test the isotropy of cosmic acceleration and…
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…
