A hybrid model of viscous and Chaplygin gas to tackle the Universe acceleration
A. Hernández-Almada, Miguel A. García-Aspeitia, M. A. Rodrírgues-Meza +1
Motivated by two seminal models proposed to explain the Universe acceleration, this paper is devoted to study a hybrid model which is constructed through a generalized Chaplygin ga…
Constraints and cosmography of CDM in presence of viscosity
L. Herrera-Zamorano, A. Hernández-Almada, Miguel A. García-Aspeitia
In this work, we study two scenarios of the Universe filled by a perfect fluid following the traditional dark energy and a viscous fluid as dark matter. In this sense, we explore t…
Stability analysis and constraints on interacting viscous cosmology
A. Hernández-Almada, Miguel A. García-Aspeitia, Juan Magaña +1
In this work we study the evolution of a spatially flat Universe by considering a viscous dark matter and perfect fluids for dark energy and radiation, including an interaction ter…
Generalized Emergent Dark Energy: observational Hubble data constraints and stability analysis
A. Hernández-Almada, Genly Leon, Juan Magaña +2
Recently \citet{PEDE:2019ApJ} proposed a phenomenologically emergent dark energy (PEDE) which consider that the dark energy density evolves as $\widetildeΩ_{\rm{DE}}(z)\,=\,Ω_{\rm{…
Gravitational waves in braneworlds after multi-messenger events
Miguel A. García-Aspeitia, Celia Escamilla-Rivera
The GW170817 event opened a new window to test modifications to General Relativity with the aim of discard or impose strong constraints in extra dimension theories of gravity. Conc…
Compact objects in unimodular gravity
J. A. Astorga-Moreno, Javier Chagoya, J. C. Flores-Urbina +1
Unimodular gravity provides a theoretical framework that allows for non-conservation of energy-momentum, with possible implications for the cosmological constant problem. It is the…
