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…
Love beyond Einstein: Metric reconstruction and Love number in quadratic gravity using WEFT
Arpan Bhattacharyya, Saptaswa Ghosh, Naman Kumar +2
We study tidal Love numbers of static black holes in four-dimensional quadratic theory of gravity, extending the result of GR. We use worldline effective field theory (WEFT) method…
Imprints of extra dimensions in eccentric extreme-mass-ratio inspirals gravitational waveforms
Shailesh Kumar, Tieguang Zi, Arpan Bhattacharyya
Studies regarding extra-dimensions have been of great interest in modern theoretical physics, including their observational consequences from future gravitational wave (GW) observa…
Gravitational waves from regular black holes in extreme mass-ratio inspirals
Shailesh Kumar, Tieguang Zi
We analyze a rotating regular black hole spacetime with an asymptotically Minkowski core, focusing on extreme mass-ratio inspiral (EMRIs) where a stellar-mass object inspirals a su…
