Unified dark sector approaches to cosmological tensions
Sergio Sevillano Muñoz, Mark Trodden
The paper analytically studies simple models where a single scalar field varies the mass of dark matter, showing how such models can simultaneously address early- and late-time cos…
Neutrino Constraints on Scalar-Tensor Gravity
Arturo de Giorgi, Ivan Martinez Soler, Sergio Sevillano Muñoz
In this work, we derive novel constraints on scalar-tensor theories from neutrino physics. Spatial variations of the background scalar field effectively generate density and positi…
The Revised Evolutionary Volume Tolman Test: Cosmological Constraints from Galaxy Evolution
Christopher J. Conselice, Edmund J. Copeland, Sergio Sevillano Muñoz
In this study we adapt a classical cosmology measurement, the volume or number density test, to a modern synthesis of observed galaxy evolution. We do this by using measured galaxy…
Updated constraints on the primordial power spectrum at sub-Mpc scales
Torsten Bringmann, Djuna Croon, Sergio Sevillano Muñoz +1
The primordial power spectrum of matter density perturbations contains highly valuable information about new fundamental physics, in particular cosmological inflation, but is only…
