Extreme mass-ratio inspirals and extra dimensions: Insights from modified Teukolsky framework
Shailesh Kumar, Tieguang Zi, Arpan Bhattacharyya
Extreme mass-ratio inspirals (EMRIs) offer a promising avenue to test extra-dimensional physics through gravitational wave (GW) observations. In this work, we study equatorial ecce…
Massive scalar fields in eccentric regime: Detectability and constraints from LISA observations of extreme mass-ratio inspirals
Tieguang Zi, Shailesh Kumar, Jun-Kun Zhao +2
Extreme mass-ratio inspirals (EMRIs) are among the prime sources for future space-borne gravitational wave (GW) observatories and provide a useful setting for testing the presence…
Dynamical Tidal Response of Regular Black Holes: Perturbative Analysis and Shell EFT Interpretation
Arpan Bhattacharyya, Naman Kumar, Shailesh Kumar
We investigate the frequency-dependent (dynamical) tidal response of regular black holes for the Bardeen, Hayward, and Fan-Wang geometries. Our results are obtained by solving the…
Gravitational memory meets astrophysical environments: exploring a new frontier through osculations
Rishabh Kumar Singh, Shailesh Kumar, Abhishek Chowdhuri +1
We study how dark matter environments influence nonlinear gravitational memory from intermediate-mass-ratio binaries. Incorporating environmental effects from the dark matter gravi…
Probing scalar field with generic extreme mass-ratio inspirals around Kerr black holes
Tieguang Zi, Shailesh Kumar
The future space-based gravitational wave observatories are expected to provide unprecedented opportunities to explore intricate characteristics of black hole binaries, particularl…
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…
