Cosmological constrains on new generalized Chaplygin gas model
Fataneh Salahedin, Reza Pazhouhesh, Mohammad Malekjani
We use different combinations of data samples to investigate the new generalized Chaplygin gas (NGCG) model in the context of dark energy (DE) cosmology. Using the available cosmol…
Comparison between different methods of model selection in cosmology
Mehdi Rezaei, Mohammad Malekjani
There are several methods for model selection in cosmology which have at least two major goals, that of finding the correct model or predicting well. In this work we discuss throug…
Cosmography approach to dark energy cosmologies: new constrains using the Hubble diagrams of supernovae, quasars and gamma-ray bursts
Mehdi Rezaei, Saeed Pour Ojaghi, Mohammad Malekjani
In the context of cosmography approach and using the data of Hubble diagram for supernovae, quasars and gamma-ray bursts, we study some DE parametrizations and also the concordance…
A Bayesian comparison between CDM and phenomenologically emergent dark energy models
M. Rezaei, T. Naderi, M. Malekjani +1
In this work we examine the recently proposed phenomenological emergent dark energy (PEDE) model by \cite{Li:2019yem}, using the latest observational data in both expansion and per…
Cosmological constrains on minimally and non-minimally coupled scalar field models
Zahra Davari, Valerio Marra, Mohammad Malekjani
We study the minimally and non-minimally coupled scalar field models as possible alternatives for dark energy, the mysterious energy component that is driving the accelerated expan…
Can dark energy be expressed as a power series of the Hubble parameter?
Mehdi Rezaei, Mohammad Malekjani, Joan Sola
In this work we examine the possibility that the dark energy (DE) density, can be dynamical and appear as a power series expansion of the Hubble rate (and its derivatives)…
