Observational constraints on viscous free- fluid in gravity
Simran Arora, Sai Swagat Mishra, P. K. Sahoo
We study the late-time cosmological dynamics of a spatially flat FLRW universe in the framework of gravity, where denotes the nonmetricity scalar. The matter sector is m…
gravity, and its cosmological implications
Ayush Hazarika, Simran Arora, P. K. Sahoo +1
Symmetric teleparallel gravity and its extensions have emerged as promising alternatives to General Relativity (GR), yet the role of explicit geometry-matter couplings remai…
Cosmological dynamics of interacting dark energy and dark matter in gravity
Gaurav N. Gadbail, Simran Arora, Phongpichit Channuie +1
In this work, we explore the behavior of interacting dark energy and dark matter within a model of gravity, employing a standard framework of dynamical system analysis. We c…
Energy conditions in the theory of gravity
Simran Arora, P. H. R. S. Moraes, P. K. Sahoo
We construct the energy conditions for the recently proposed gravity theory, for which is a generic function of the Ricci scalar , matter lagrangian density a…
Reconstruction of the singularity-free gravity via Raychaudhuri equations
Gaurav N. Gadbail, Simran Arora, P. K. Sahoo +1
We study the bounce cosmology to construct a singularity-free model using the reconstruction technique. The formulation of the model is based on t…
Revisiting kink-like parametrization and constraints using OHD/Pantheon+/BAO samples
Simran Arora, P. K. Sahoo
We reexamine the kink-like parameterization of the deceleration parameter to derive constraints on the transition redshift from cosmic deceleration to acceleration. This is achieve…
