Quasinormal modes of a dyonic black hole in Einstein-Euler-Heisenberg theory
Shubham Kala, Abhishek Negi, Hemwati Nandan
In this study, we investigate the quasinormal modes of a non-rotating dyonic black hole within the framework of Einstein-Euler-Heisenberg theory. We present a detailed analysis foc…
Shadow and weak gravitational lensing of a rotating regular black hole in a non-minimally coupled Einstein-Yang-Mills theory in the presence of plasma
Shubham Kala, Hemwati Nandan, Prateek Sharma
The null geodesics of the regular and rotating magnetically charged black hole in a non-minimally coupled Einstein-Yang-Mills theory surrounded by a plasma medium is studied. The e…
Stability of circular geodesics in equatorial plane of Kerr spacetime
Pradeep Singh, Hemwati Nandan, Lokesh Kumar Joshi +2
We analyze the stability of circular geodesics for timelike as well as null geodesics of the Kerr BH spacetime with rotation parameter on the equatorial plane by Lyapunov stability…
Stability analysis of circular orbits around a traversable wormhole with massless conformally coupled scalar field
Shobhit Giri, Hemwati Nandan, Lokesh Kumar Joshi +1
We study the stability of circular orbits in the background of a traversable wormhole (TWH) spacetime obtained as a solution of Einstein's field equations coupled conformally to a…
Geodesic stability and quasinormal modes of non-commutative Schwarzschild black hole employing Lyapunov exponent
Shobhit Giri, Hemwati Nandan, Lokesh Kumar Joshi +1
We study the dynamics of test particle and stability of circular geodesics in the gravitational field of a non-commutative geometry inspired Schwarzschild black hole spacetime (NCS…
Efficiency of Penrose process in spacetime of axially symmetric magnetized Reissner-Nordström black hole
Sanjar Shaymatov, Pankaj Sheoran, Ricardo Becerril +2
In this paper, we investigate the Penrose process in the purlieus of the axially symmetric magnetized Reissner-Nordström black hole for both neutral and charged particles. We start…
