How parameter constraining can influence the mass accretion process of a Black Hole in the Generalized Rastall Gravity Theory ?
Puja Mukherjee, Ujjal Debnath, Himanshu Chaudhary +1
Black holes, one of the greatest enigmas of our Universe, are challenging to decipher. This work is dedicated to observing the changes in the mass of a non-singular black hole with…
Cosmological tests of the dark energy models in Finsler-Randers Space-time
Z. Nekouee, Himanshu Chaudhary, S. K. Narasimhamurthy +2
The Finsler-Randers space-time offers a novel perspective on cosmic dynamics, departing from the constraints of General Relativity. This paper thoroughly investigates two dark ener…
