Temperature of free gravitational field: A geometrical perspective
Samarjit Chakraborty, Gareth Amery, Sunil D Maharaj +1
In this paper, using a novel geometrical approach, we relate the concept of the thermodynamic temperature of the free gravitational field, to the non-affinity of real null geodesic…

Ricci-Weyl curvature balance in viscous dissipative collapse: A covariant analysis of singularity censorship
Samarjit Chakraborty, Rituparno Goswami, Sunil D. Maharaj +1
We investigate the cosmic censorship conjecture in a spherically symmetric collapse with shear and bulk viscosity, heat flux, and pressure anisotropy, imposing physically reasonabl…

Gradient conformal stationarity and the CMC condition in LRS spacetimes
Gareth Amery, Peter K S Dunsby, Abbas M Sherif
We study the existence of gradient conformal Killing vectors (CKVs) in the class of locally rotationally symmetric (LRS) spacetimes which generalizes spherically symmetric spacetim…
