Spinning test particles in a weak gravitational wave and the memory effect
Ritwik Acharyya, Shailesh Kumar, Sayan Kar
In this work, we investigate the worldline deviation of spinning test particles in a weak gravitational wave (GW) spacetime. Within the pole-dipole approximation and the Tulczyjew…
Massive scalar fields in eccentric regime: Detectability and constraints from LISA observations of extreme mass-ratio inspirals
Tieguang Zi, Shailesh Kumar, Jun-Kun Zhao +3
Extreme mass-ratio inspirals (EMRIs) are among the most promising sources for future space-based gravitational wave (GW) observatories and provide sensitive probes of additional fu…
Dynamical tidal response of regular black holes: Perturbative analysis and shell EFT interpretation
Arpan Bhattacharyya, Naman Kumar, Shailesh Kumar
We compute the frequency-dependent quadrupolar tidal response of Bardeen, Hayward, and Fan-Wang regular black holes in the polar and axial sectors by solving the coupled gravitatio…
Probing beyond-vacuum general relativistic effects with extreme mass-ratio inspirals
Tieguang Zi, Mostafizur Rahman, Shailesh Kumar
We examine extreme mass-ratio inspirals (EMRIs) as probes of beyond-vacuum general relativistic effects, accounting for both astrophysical environments and scalar Gauss-Bonnet (sGB…
