Arrow of time problem in gravitational collapse
Samarjit Chakraborty, Sunil D. Maharaj, Rituparno Goswami +1
We investigate the arrow of time problem in the context of gravitational collapse of radiating stars in higher dimensions for both neutral and charged matter. The interior spacetim…
Complexity and structure scalars of Type II matter fields
Samarjit Chakraborty, Rituparno Goswami, Sunil D. Maharaj
A general semi-tetrad covariant approach is adopted to analyse the structure scalars of a Type II fluid in generalized Vaidya spacetime. The relationship between the covari…
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…
Absence of curvature singularities in symmetric perfect fluid spacetimes in Einstein-Gauss-Bonnet Gravity
Aavishkar Madhunlall, Chevarra Hansraj, Rituparno Goswami +1
In this paper we study the higher dimensional homogeneous and isotropic perfect fluid spacetimes in Einstein-Gauss-Bonnet (EGB) gravity. We solve the modified field equations with…
