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…
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…
A model of dark matter dark energy interaction with some cosmic consequences
J. K. Singh, Ritika Nagpal
In this study, we will look at an interacting dark energy model. In the framework of Friedmann-Robertson-Walker (FRW) space-time, we have made the hypothesis of an interacting sche…
Reconstructing cosmic evolution with a density parametrization
Ritika Nagpal, Shibesh Kumar Jas Pacif, Abhishek Parida
The current paper provides a comprehensive examination of a dark energy cosmological model in the classical regime, in which a generic scalar field is regarded as a dark energy sou…
Cosmological aspects of gravity in a simple model with a parametrization of
Ritika Nagpal, Shibesh Kumar Jas Pacif
In this paper, we have considered a quadratic variation of the deceleration parameter () as a function of cosmic time () which describes a smooth transition from the decelera…
FLRW cosmology with EDSFD parametrization
J. K. Singh, Ritika Nagpal
In this paper, we study a cosmological model in the background of FLRW space time by assuming an appropriate parametrization in the form of a differential equation in terms of ener…
Cosmological aspects of a hyperbolic solution in gravity
Ritika Nagpal, J. K. Singh, A. Beesham +1
This article deals with a cosmological scenario in gravity for a flat FLRW model of the universe. We consider the function as which starts with…
Bouncing cosmology in gravity
J. K. Singh, Kazuharu Bamba, Ritika Nagpal +1
A cosmological model with a specific form of the Hubble parameter is constructed in a flat homogeneous, and isotropic background in the framework of gravity, where is…
FLRW cosmological models with quark and strange quark matters in f(R,T) gravity
Ritika Nagpal, J. K. Singh, S. Aygün
In this paper, we have studied the magnetized quark matter (QM) and strange quark matter (SQM) distributions in the presence of gravity in the background of Friedmann--Le…
Analysis with observational constraints in -cosmology in gravity
Ritika Nagpal, S. K. J. Pacif, J. K. Singh +2
An exact cosmological solution of Einstein field equations (EFEs) is derived for a dynamical vacuum energy in gravity for Friedmann-Lemaitre-Robertson-Walker (FLRW) space-…
Statefinder diagnostic for modified Chaplygin gas cosmology in f(R,T) gravity with particle creation
