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…
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…
Large scale structure constraints and matter power spectrum in gravity
Praveen Kumar Dhankar, Albert Munyeshyaka, Saddam Hussain +1
In the present work, we take into account the dynamical system analysis to investigate the matter power spectrum within the framework of the gravitational th…
Probing the Dynamics of Gaussian Dark Energy Equation of State Using DESI BAO
Saddam Hussain, Simran Arora, Anzhong Wang +1
We present an updated reconstruction of the DE equation of state (EoS), , employing the newly released DESI DR2 Baryon Acoustic Oscillation data. This analysis constrains the…
