CDM model: A promising scenario for alleviation of cosmological tensions
Ozgur Akarsu, Eleonora Di Valentino, Suresh Kumar +3
We present a comprehensive analysis of the CDM model, which explores the recent conjecture suggesting a rapid transition of the Universe from anti-de Sitter vacua to de…
Cosmological models in scale-independent energy-momentum squared gravity
Ozgur Akarsu, N. Merve Uzun
Scale-independent EMSG is a particular model of energy-momentum squared gravity (EMSG) in which the new terms in the Einstein field equations arising from the EMSG theory enter wit…
CDM cosmology with a quiescent anisotropy in a higher dimensional steady state universe
Ozgur Akarsu, Tekin Dereli, Nihan Katirci
In this work, which follows a series of studies on the higher-dimensional steady state universe idea and prepared for Professor Tekin Dereli's Festschrift, we show the influence of…
Constraints on a Bianchi type I spacetime extension of the standard CDM model
Ozgur Akarsu, Suresh Kumar, Shivani Sharma +1
We consider the simplest anisotropic generalization, as a correction, to the standard CDM model, by replacing the spatially flat Robertson-Walker metric by the Bianchi type-I me…
A divergence-free parametrization for dynamical dark energy
Ozgur Akarsu, Tekin Dereli, J. Alberto Vazquez
We introduce a new parametrization for the dark energy, led by the same idea to the linear expansion of the equation of state in scale factor and in redshift , which diverge…
Accelerated expansion of the Universe a la the Stueckelberg mechanism
Ozgur Akarsu, Metin Arik, Nihan Katirci +1
We investigate a cosmological model in which the Stueckelberg fields are non-minimally coupled to the scalar curvature in a gauge invariant manner. We present not only a solution t…
