Cosmological constraints on the Multi Scalar Field Dark Matter model
L. O. Téllez-Tovar, Tonatiuh Matos, J. Alberto Vázquez
The main aim of this paper is to provide cosmological constraints on the Multi Scalar Field Dark Matter model (MSFDM), in which we assume the dark matter is made up of different ul…
Model selection applied to reconstructions of the Dark Energy
Luis A. Escamilla, J. Alberto Vazquez
The main aim of this paper is to perform a model comparison for some reconstructions of the key properties that describe the dark energy of the Universe i.e. energy density and the…
Relaxing cosmological tensions with a sign switching cosmological constant
Ozgur Akarsu, Suresh Kumar, Emre Ozulker +1
Inspired by the recent conjecture originated from graduated dark energy that the Universe has recently transitioned from anti-de Sitter vacua to de Sitter vacua, we extend the C…
Simple-graduated dark energy and spatial curvature
Giovanni Acquaviva, Ozgur Akarsu, Nihan Katirci +1
In this work, we first discuss the possibility that dark energy models with negative energy density values in the past can alleviate the tension, as well as the discrepancy w…
Neural network reconstructions for the Hubble parameter, growth rate and distance modulus
Isidro Gómez-Vargas, Ricardo Medel Esquivel, Ricardo García-Salcedo +1
This paper introduces a new approach to reconstruct cosmological functions using artificial neural networks based on observational measurements with minimal theoretical and statist…
