Reconstruction of dark energy density by non-parametric approaches
Ahmad Mehrabi, Maryam Vazirnia
The evolution of dark energy density is a crucial quantity in understanding the nature of dark energy. Often, the quantity is described by the so-called equation of state, that is…
Using newest VLT-KMOS HII Galaxies and other cosmic tracers to test the CDM tension
Ahmad Mehrabi, Spyros Basilakos, Pavlina Tsiapi +8
We place novel constraints on the cosmokinetic parameters by using a joint analysis of the newest VLT-KMOS HII galaxies (HIIG) with the Supernovae Type Ia (SNIa) Pantheon sample. W…
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…
Does CDM really be in tension with the Hubble diagram data?
Ahmad Mehrabi, Spyros Basilakos
In this article, we elaborate further on the CDM "tension", suggested recently by the authors \cite{Lusso:2019akb,Risaliti:2018reu}. We combine Supernovae type Ia (SNIa) with qu…
The growth of DM and DE perturbations in DBI non-canonical scalar field scenario
K. Rezazadeh, S. Asadzadeh, K. Fahimi +2
We study the effect of varying sound speed on clustering dark energy in the Dirac-Born-Infeld (DBI) scenario. The DBI action is included in the class of -essence models, and it…
Flare Activity and Magnetic Feature Analysis of the Flare Stars
Hadis Goodarzi, Ahmad Mehrabi, Habib khosroshahi +1
We analyze the light curve of 1740 flare stars to study the relationship between the magnetic feature characteristics and the identified flare activity. Coverage and stability of m…
