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…
