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…
