Maxwell theories along the light track: Null Formalism in extended electrodynamics
Zhi Xiao, Bing Sun, Tao Zhu
We develop a differential-form approach to systematically derive the Newman-Penrose null-tetrad equations for Lorentz-violating extensions of Maxwell electrodynamics. The coordinat…
Exploring the accelerating black holes from the observations of quasi-periodic oscillations in X-ray binaries
Hamza Rehman, Saddam Hussain, G. Abbas +1
Black holes in dense astrophysical environments, such as globular clusters or in the vicinity of other massive objects, may possess accelerations. Such acceleration would modulate…
Interacting -essence field with non-pressureless Dark Matter: Cosmological Dynamics and Observational Constraints
Saddam Hussain, Qiang Wu, Tao Zhu
We investigate a class of interacting dark energy and dark matter (DM) models, where dark energy is modeled as a -essence scalar field with an inverse-square potential. Two gene…
Constraints on extra charges in dyonic Kerr-Newman-Kasuya-Taub-NUT black hole from the observations of quasi-periodic oscillations
Hamza Rehman, Saddam Hussain, Ghulam Abbas +1
This paper investigates the influence of the dimensionless electric charge (), magnetic charge (), and Taub-NUT parameter () of a dyonic Kerr-Newman-Kasuya-Taub-NUT…
Corrections to Hawking-like Radiation for a Friedmann-Robertson-Walker Universe
Tao Zhu, Ji-Rong Ren
Recently, a Hamilton-Jacobi method beyond semiclassical approximation in black hole physics was developed by \emph{Banerjee} and \emph{Majhi}\cite{beyond0}. In this paper, we gener…
