Is Dark Energy Changing? Probing the Universe's Expansion with present and future astronomical probes
Mehdi Rezaei, Supriya Pan, Weiqiang Yang +1
This study explores the possibility of a time-varying dark energy (DE) equation of state (EoS) deviating from -1. We employ a comprehensive dataset of usual astronomical probes (Ty…
Oscillating dark energy in light of the latest observations and its impact on the Hubble tension
Mehdi Rezaei
In this paper we have performed a comparative study of different types of oscillating dark energy models using the Metropolis algorithm of MCMC. Eight different oscillating paramet…
Evidence of dynamical dark energy in a non-flat universe: current and future observations
Mehdi Rezaei, Supriya Pan, Weiqiang Yang +1
We investigate the dark energy phenomenology in an extended parameter space where we allow the curvature density of our universe as a free-to-vary parameter. The inclusion of the c…
Running vacuum versus Holographic dark energy: a cosmographic comparison
Mehdi Rezaei, Joan Sola Peracaula
We perform a comparative study of different types of dynamical dark energy models (DDES) using the cosmographic method. Among the models being examined herein we have the Running V…
Cosmographic parameters in model-independent approaches
Ahmad Mehrabi, Mehdi Rezaei
Cosmographic approach, a Taylor expansion of the Hubble function, has been used as a model-independent method to investigate the evolution of the universe in the presence of cosmol…
Cosmographic approach to Running Vacuum dark energy models: new constraints using BAOs and Hubble diagrams at higher redshifts
Mehdi Rezaei, Joan Sola, Mohammad Malekjani
In this work we study different types of dark energy (DE) models in the framework of the cosmographic approach, with emphasis on the Running Vacuum models (RVMs). We assess their v…
