Quadrupole and quadratic-in-spin effects in quasicircular, spinning, asymmetric binaries
Mostafizur Rahman, Misbah Shahzadi, Adam Pound +1
Next-generation gravitational-wave detectors will require significant improvements in current theoretical waveform models, particularly in the case of asymmetric-mass binaries. Her…
Spinning charged test particle dynamics around a Schwarzschild black hole embedded in a homogeneous magnetic field
Misbah Shahzadi, Martin Kolos, Ondrej Zelenka +1
We study the dynamics of spinning charged test particles orbiting a Schwarzschild black hole immersed in a test uniform magnetic field. This setup provides a simple but physically…
Circular equatorial orbits of extended bodies with spin-induced quadrupole around a Kerr black hole: Comparing spin-supplementary conditions
Misbah Shahzadi, Georgios Lukes-Gerakopoulos, Martin Kološ
The worldline of an extended body in curved spacetime can be described by the Mathisson-Papapetrou-Dixon equations when its centroid, i.e., its center of mass, is fixed by a spin s…
Structure-preserving numerical simulations of test particle dynamics around slowly rotating neutron stars within Hartle-Thorne approach
Misbah Shahzadi, Martin Kolos, Rabia Saleem +2
In this paper, we explore the chaotic signatures of the geodesic dynamics for particles moving in the slowly rotating Hartle-Thorne spacetime; an approximate solution of vacuum Ein…
Testing alternative spacetimes by high-frequency quasi-periodic oscillations observed in microquasars and active galactic nuclei
Misbah Shahzadi, Martin Kološ, Rabia Saleem +1
In this article, we try to capture the influence of deviation from standard Kerr black hole spacetime on observed high-frequency quasi-periodic oscillations signal. We explore the…
Charged particle dynamics in parabolic magnetosphere around Schwarzschild black hole
Martin Kološ, Misbah Shahzadi, Arman Tursunov
The study of charged particle dynamics in the combined gravitational and magnetic field can provide important theoretical insight into astrophysical processes around black holes. I…
Testing alternative theories of gravity by fitting the hot-spot data of Sgr A*
Misbah Shahzadi, Martin Kološ, Zdeněk Stuchlík +1
We are fitting dynamics of electrically neutral hot-spot orbiting around Sgr A* source in Galactic center, represented by various modifications of the standard Kerr black hole (BH)…
Epicyclic oscillations in spinning particle motion around Kerr black hole applied in models fitting the quasi-periodic oscillations observed in quasars and microquasars
Misbah Shahzadi, Martin Kološ, Zdeněk Stuchlík +1
The study of the quasi-periodic oscillations (QPOs) of X-ray flux observed in the stellar-mass black hole (BH) binaries or quasars can provide a powerful tool for testing the pheno…
Particle collisions in ergoregion of braneworld Kerr black hole
Saeed Ullah Khan, Misbah Shahzadi, Jingli Ren
This paper explores the neutral particle motion and collisional Penrose process in ergoregion of the braneworld Kerr black hole. We analyze the properties of event horizon, ergosph…
Circular Motion and Energy Extraction in a Rotating Black Hole
M. Shahzadi, Z. Yousaf, Saeed Ullah Khan
This paper explores the circular geodesics of neutral test particles on an equatorial plane around a rotating black hole. After using equations of motion of scalar-tensor-vector gr…
Particle Dynamics Near Kerr-MOG Black Hole
M. Sharif, Misbah Shahzadi
This paper explores the dynamics of both neutral as well as charged particles orbiting near a rotating black hole in scalar-tensor-vector gravity. We study the conditions for the p…
