SSFDE Model: Cosmological Implications and Dynamical System Analysis
Ritika Nagpal, Anil Kandel, Ratul Mandal +2
In this paper, we consider an interacting scalar field dark energy model with an exponential potential and a dark sector coupling \( Q = 3γHρ_{dm} \), which has been observationall…
Observational tests of the conformal osculating Barthel-Kropina cosmological model
Himanshu Chaudhary, Rattanasak Hama, Tiberiu Harko +2
We consider detailed cosmological tests of dark energy models obtained from the general conformal transformation of the Kropina metric, representing an -type Finslerian geom…
Dark Sector Interactions: Probing the Hubble Parameter and the Sound Horizon
Ritika Nagpal, S. K. J. Pacif, Farruh Atamurotov +1
In this study, we explore the impact of the interacting parameter on dark matter in a model resulting from a parametrization of dark energy density. To ensure a model-independent a…
Cosmological tests of the dark energy models in Finsler-Randers Space-time
Z. Nekouee, Himanshu Chaudhary, S. K. Narasimhamurthy +2
The Finsler-Randers space-time offers a novel perspective on cosmic dynamics, departing from the constraints of General Relativity. This paper thoroughly investigates two dark ener…
Estimation of and in the Parameterization within Einstein and Horava-Lifshitz Gravity Using DESI-Y1 and SDSS-IV
Ujjal Debnath, Himanshu Chaudhary, Niyaz Uddin Molla +2
We present a novel dynamical dark energy model within the frameworks of both Einstein gravity and Horava-Lifshitz gravity. Utilizing CDMMA parametrization of the dark energy equati…
Cosmic evolution in gravity: Exploring a higher-order time-dependent function of deceleration parameter with observational constraints
Madhur Khurana, Himanshu Chaudhary, Saadia Mumtaz +2
In this research paper, we explore a well-motivated parametrization of the time-dependent deceleration parameter, characterized by a cubic form, within the context of late time cos…
