The Universe acceleration from the Unimodular gravity view point: Background and linear perturbations
Miguel A. García-Aspeitia, A. Hernández-Almada, Juan Magaña +1
With the goal of studying the cosmological constant (CC) problem, we present an exhaustive analysis of unimodular gravity as a possible candidate to resolve the CC origin and with…
Cosmological test on viscous bulk models using Hubble Parameter measurements and type Ia Supernovae data
A. Hernández-Almada
From a phenomenological point of view, we analyze the dynamics of the Universe at late times by introducing a polynomial and hyperbolic bulk viscosity into the Einstein field equat…
Cosmic acceleration in unimodular gravity
Miguel A. García-Aspeitia, C. Martínez-Robles, A. Hernández-Almada +2
We study unimodular gravity in the context of cosmology, particularly some interesting consequences that might be able to describe the background cosmology and the late cosmic acce…
