BBN to Late-Time Acceleration in Gravity

Sai Swagat Mishra, Suchita Patel, P. K. Sahoo

We present, to our knowledge, the first systematic study of early-late cosmic evolution and acceleration in the framework of gravity, an extension of teleparal…

Cosmological Evolution of the Universe in Torsion-based Modified Gravity

Sai Swagat Mishra

General Relativity, despite its century-long success, faces conceptual and observational challenges, including singularities, incompatibility with quantum mechanics, and the need t…

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…

Chebyshev cosmography in the framework of extended symmetric teleparallel theory

Sai Swagat Mishra, N. S. Kavya, P. K. Sahoo +1

Cosmography has been extensively utilized to constrain the kinematic state of the Universe using measured distances. In this work, we propose a new method to reconstruct coupling t…

Investigating early and late-time epochs in gravity

Ameya Kolhatkar, Sai Swagat Mishra, P. K. Sahoo

In the following work, a new hybrid model of the form has been proposed and confronted using both early as well as late-time constraints. We first…

Can models play a bridge between early and late time Universe?

N. S. Kavya, Sai Swagat Mishra, P. K. Sahoo +1

The ability of Big Bang Nucleosynthesis theory to accurately predict the primordial abundances of helium and deuterium, as well as the baryon content of the Universe, is considered…
