Reconstruction of a dark energy model for the Dirac-Born-Infeld scalar field with the Hubble and DESI data via Gaussian process
Sayantan Ghosh, Gaurav N. Gadbail, P. K. Sahoo +1
In this study, we reconstruct the dark energy (DE) as a Dirac-Born-Infeld (DBI) scalar field from the Hubble dataset (32 CC + 26 BAO) and the DESI dataset using the Gaussian proces…
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…
