Black Holes as Catalysts for Cosmic String Detection and Axion Dark Matter Genesis
Ishan Swamy, Deobrat Singh
The global Peccei-Quinn (PQ) symmetry, proposed to resolve the strong CP problem, predicts the existence of the axion, a pseudo Nambu-Goldstone boson and a leading dark…
Blandford-Znajek Jets and the Total Angular Momentum Evolution of a Black Hole Connected to a Cosmic String
Ishan Swamy, Deobrat Singh
Rotating black holes with strong magnetic fields lead to an outward energy flux in the form of jets governed by the Blandford-Znajek mechanism. These jets depend on factors such as…
Investigating the interaction of a Cosmic String with an Accreting Black Hole
Ishan Swamy, Deobrat Singh
Rotating black holes when attached to a cosmic string have their rotational energy extracted leading to a change in its spin and mass. The spin of a black hole can be measured usin…
Probing Cosmic Strings via Black Hole Quasinormal Modes in Gravitational Wave Astronomy
Ishan Swamy, Deobrat Singh
Black holes, the simplest solution to Einstein's field equations, do not emit light, making their observations a major challenge for researchers. However, discovery of binary black…
Impact on orbital period of X-ray Binary system attached to a cosmic string
Ishan Swamy, Deobrat Singh
Cosmic strings attached to rotating black holes extract its rotational energy, resulting in a mass loss and reduced spin. In this paper we discuss the proposed methods to detect th…
