Quasinormal modes of the generalized JMN naked singularity using exact WKB analysis
Aryansh Saxena, Suresh C. Jaryal, K. K. Sharma
In this paper, we study the quasinormal modes of the generalized Joshi-Malafarina-Narayan (JMN) naked singularity spacetime using the exact Wentzel-Kramers-Brillouin (WKB) method.…

Spherical trapped surfaces in n-dimensional general relativity
Ayan Chatterjee, Suresh C. Jaryal, Akshay Kumar
In this paper, we examine gravitational collapse of matter fields in -dimensional general relativity. The matter energy-momentum tensor under consideration includes dust, perfec…

Gravitational collapse in pure Gauss- Bonnet theory
Akshay Kumar, Ayan Chatterjee, Suresh C. Jaryal
In this paper, we study the gravitational collapse of matter fields, which include dust, perfect fluids as well as fluids admitting bulk and shear viscosity. The initial conditions…
