Constraining a model supported in Moiré gravity with a recent data release
J. A. Astorga-Moreno, Miguel A. García-Aspeitia, A. Hernández-Almada +1
Moiré theory is a revolutionary alternative arising from solid-state physics that can be extended to gravity, forming a framework called Moiré gravity. The idea behind it is that E…
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…
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…
Noncommutative Quantum Cosmology for the FLRW model in Unimodular Gravity
J. A. Astorga-Moreno, Miguel A. García-Aspeitia, E. A. Mena-Barboza
It is well known that classical Unimodular Gravity (UG) is equivalent to General Relativity, but is not clear the equivalence at the quantum level. Here we exhibit, in the UG frame…
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…
Asymptotically Equivalent Functions and Ultrafilters applied to Noncommutative Quantum Cosmology
J. A. Astorga-Moreno, E. Mena, Miguel A. Garcia-Aspeitia
Using the semi-classical approximation to the Wheeler-DeWitt equation obtained via Arnowitt-Deser-Misner (ADM) formalism in the Friedmann-Lemaitre-Robertson-Walker (FLRW) model cou…
The presence of a Phantom field in a Randall-Sundrum scenario
Rubén O. Acuña-Cárdenas, J. A. Astorga-Moreno, Miguel A. Garcia-Aspeitia +1
The presence of phantom dark energy in brane world cosmology generates important new effects, causing a premature Big Rip singularity when we increase the presence of extra dimensi…
