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 \( Q = 3γHÏ_{dm} \), which has been observationa…
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 ge…
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…
Extracting and in Pacif Parametrization Models through Late-Time Dataset
Himanshu Chaudhary, Shibesh Kumar Jas Pacif, G. Mustafa +2
This study examines five models derived from the Pacif parametrization scheme of the Hubble parameter (), yielding various linear to quintic forms of the deceleration parameter…
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…
