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…
