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…
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…
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…
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…
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…
