Cosmology under the fractional calculus approach: a possible tension resolution?

Genly Leon, Miguel A. García-Aspeitia, Guillermo Fernandez-Anaya +3

Recently, a new field of study called fractional cosmology has emerged. It uses fractional calculus to modify the standard derivative equations and change the Friedmann equations.…

Constraining uber gravity with recent observations and studying the problem

Gustavo A. Concha Valdez, Claudia Quintanilla, Miguel A. García-Aspeitia +2

This paper studies both CDM and CDM models under the über gravity theory, named üCDM and üCDM respectively. We report bounds over their parameter phase-space using several co…

An exponential equation of state of dark energy in the light of 2018 CMB Planck data

Mónica N. Castillo-Santos, A. Hernández-Almada, Miguel A. García-Aspeitia +1

The dynamics of the Universe is analyzed using an exponential function for the dark energy equation of state, known as Gong-Zhang parameterization. The phase space of the free para…

Observational constraints and dynamical analysis of Kaniadakis horizon-entropy cosmology

A. Hernández-Almada, Genly Leon, Juan Magaña +5

We study the scenario of Kanadiakis horizon entropy cosmology which arises from the application of the gravity-thermodynamics conjecture using the Kaniadakis modified entropy. The…

Kaniadakis holographic dark energy: observational constraints and global dynamics

A. Hernández-Almada, Genly Leon, Juan Magaña +4

We investigate Kaniadakis-holographic dark energy by confronting it with observations. We perform a Markov Chain Monte Carlo analysis using cosmic chronometers, supernovae type Ia,…

Einstein-Gauss-Bonnet gravity: is it compatible with modern cosmology?

Miguel A. García-Aspeitia, A. Hernández-Almada

Einstein-Gauss-Bonnet (EGB) model is recently restudied in order to analyze new consequences in gravitation, modifying appropriately the Einstein-Hilbert action. The consequences i…

Linear perturbations spectra for dynamical dark energy inspired by modified gravity

Celia Escamilla-Rivera, A. Hernández-Almada, Miguel A. García-Aspeitia +1

In this paper, we study a particular modified gravity Equation of State, the so-called Jaime-Jaber-Escamilla, that emerges from the first gravity modified action principle and can…
