Observational Constraints and Cosmological Implications of Scalar-Tensor Gravity
Amine Bouali, Himanshu Chaudhary, Tiberiu Harko +3
Recently, the scalar-tensor representation of gravity was used to explore gravitationally induced particle production/annihilation. Using the framework of irreversible th…
Viscous fluid dynamics with decaying vacuum energy density
C. P. Singh, Vinita Khatri
In this work, we investigate the dynamics of bulk viscous models with decaying vacuum energy density (VED) in a spatially homogeneous and isotropic flat Friedmann-Lemaître- Roberts…
Addressing the Tension using Late-Time Observational Measurements in a Novel deceleration Parametrization
Himanshu Chaudhary, Ujjal Debnath, G. Mustafa +2
This paper introduces a novel cosmological model aimed at probing the accelerated expansion of the late Universe through a unique parametrization of the deceleration parameter. We…

In this paper, a well-motivated parametrization of the Hubble parameter (% ) is revisited that renders two models of dark energy showing some intriguing features of the late-tim…
Cosmological tests of the osculating Barthel-Kropina dark energy model
Amine Bouali, Himanshu Chaudhary, Rattanasak Hama +3
We further investigate the dark energy model based on the Finsler geometry inspired osculating Barthel-Kropina cosmology. The Barthel-Kropina cosmological approach is based on the…
Constraints on the Parameterized Deceleration Parameter in FLRW Universe
Himanshu Chaudhary, Amine Bouali, Ujjal Debnath +2
Confirmation of accelerated expansion of the universe probed the concept of dark energy theory, and since then, numerous models have been introduced to explain its origin and natur…
