Ringdown of Charged Compact Objects using Membrane Paradigm
Mostafizur Rahman, Arpan Bhattacharyya
Although the black holes are an integral part of the standard model of astrophysics and cosmology, their existence poses some serious fundamental problems. In recent years, several…
Strong cosmic censorship conjecture with NUT charge and conformal coupling
Mostafizur Rahman, Soumodeep Mitra, Sumanta Chakraborty
Strong cosmic censorship conjecture is central to the deterministic nature of general relativity, since it asserts that given any generic initial data on a spacelike hypersurface,…
On the validity of Strong Cosmic Censorship Conjecture in presence of Dirac fields
Mostafizur Rahman
A well posed theory of nature is expected to determine the future of an observer uniquely from a given set of appropriate initial data. In the context of general relativity, this i…
Fate of Strong Cosmic Censorship Conjecture in Presence of Higher Spacetime Dimensions
Mostafizur Rahman, Sumanta Chakraborty, Soumitra SenGupta +1
Strong cosmic censorship conjecture has been one of the most important leap of faith in the context of general relativity, providing assurance in the deterministic nature of the as…
Astrophysical Signatures of Black holes in Generalized Proca Theories
Mostafizur Rahman, Anjan A. Sen
Explaining the late time acceleration is one of the most challenging tasks for theoretical physicists today. Infra-red modification of Einstein's general theory of relativity (GR)…
Black Hole Topology in Gravity
Akash K Mishra, Mostafizur Rahman, Sudipta Sarkar
Hawking's topology theorem in general relativity restricts the cross-section of the event horizon of a black hole in dimension to be either spherical or toroidal. The toroida…
