A comparative study of emergent dark energy models
Andrés García-Rivera, A. Hernández-Almada, Miguel A. García-Aspeitia +1
Late (emergent) dark energy models that involve a hyperbolic tangent in their dynamic equations have achieved success due to their simplicity, the possibility of resolving the Hubb…
DESI and fast radio burst used to constrain modified theories of gravity
J. A. Astorga-Moreno, Miguel A. García-Aspeitia, A. Hernández-Almada +1
This paper is devoted to the study of the viability of DESI and the fast radio burst to constrain the free parameters of modified theories of gravity. Thus, we present a model supp…
On a model of variable curvature that mimics the observed Universe acceleration
A. Esteban-Gutiérrez, Miguel A. García-Aspeitia, A. Hernández-Almada +2
We present a new model based on General Relativity in where a subtle change of curvature at late times is able to produce the observed Universe acceleration and an oscillating beha…
Phenomenological emergent dark energy in the light of DESI Data Release 1
A. Hernández-Almada, M. L. Mendoza-Martínez, Miguel A. García-Aspeitia +1
This manuscript revisits the phenomenological emergent dark energy model (PEDE) by confronting it with recent cosmological data from early and late times. In particular we analyze…
ΛCDM-Rastall cosmology revisited: constraints from a recent Quasars datasample
Jesús Astorga-Moreno, Kyra Jacobo, Salvador Arteaga +2
In this paper we study the impact of a recent quasar datasample in the constraint of the free parameters of an extension of general relativity. As a ruler to test, we use Rastall g…
Synchronize your \textit{chrono-brane}: Testing a variable brane tension model with strong gravitational lensing
Tomás Verdugo, Mario H. Amante, Juan Magaña +3
Brane world models have shown to be promising to understand the late cosmic acceleration, in particular because such acceleration can be naturally derived, mimicking the dark energ…
Taxonomy of Dark Energy Models
V. Motta, Miguel A. García-Aspeitia, A. Hernández-Almada +2
The accelerated expansion of the Universe is one of the main discoveries of the past decades, indicating the presence of an unknown component: the dark energy. Evidence of its pres…
Constraining a causal dissipative cosmological model
Norman Cruz, A. Hernández-Almada, Octavio Cornejo-Pérez
In this paper a cosmological solution of polynomial type for the causal thermodynamical approach of Isarel-Stewart, found in \cite{MCruz:2017, Cruz20…
Probing dark energy with braneworld cosmology in the light of recent cosmological data
Miguel A. Garcia-Aspeitia, Juan Magaña, Alberto Hernandez-Almada +1
We investigate a brane model based on Randall-Sundrum scenarios with a generic dark energy component. The latter drives the accelerated expansion at late times of the Universe. In…
