How Complex is Dark Energy? A Bayesian Analysis of CPL Extensions with Recent DESI BAO Measurements
Mohammad Malekjani, Saeed Pourojaghi, Zahra Davari
The nature of dark energy is one of the big puzzling issues in cosmology. While CDM provides a good fit to the observational data, evolving dark energy scenarios, such as the CP…
CDM model against cosmography: A possible deviation after DESI 2024
Saeed Pourojaghi, Mohammad Malekjani, Zahra Davari
In this study, we present an analysis of the standard flat-CDM model using a cosmographic approach, incorporating recent DESI BAO observations and Supernovae Type Ia catalogues…
Cosmological constraints on dark energy parametrizations after DESI 2024: Persistent deviation from standard CDM cosmology
M. Malekjani, Z. Davari, S. Pourojaghi
In this work, we present a study on cosmological constraints of dark energy (DE) parametrizations after the observations of Dark Energy Spectroscopic Instruments (DESI) for Baryon…
MOG cosmology without dark matter and the cosmological constant
Zahra Davari, Sohrab Rahvar
In this work, we investigate the MOdified Gravity (MOG) theory for dynamics of the universe and compare the results with the CDM cosmology. We study the background cosmological…
Agegraphic dark energy: growth index and cosmological implications
M. Malekjani, S. Basilakos, A. Mehrabi +2
We study the main cosmological properties of the agegraphic dark energy model at the expansion and perturbation levels. Initially, using the latest cosmological data we implement a…
Growth of matter perturbations in clustered holographic dark energy cosmologies
Ahmad Mehrabi, Spyros Basilakos, Mohammad Malekjani +1
We investigate the growth of matter fluctuations in holographic dark energy cosmologies. First we use an overall statistical analysis involving the latest observational data in ord…
