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…
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…
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…
Probing dark matter halo profiles with multi-band observations of gravitational waves
Divya Tahelyani, Arpan Bhattacharyya, Anand S. Sengupta
In this paper, we evaluate the potential of multiband gravitational wave observations from a deci-Hz space-based detector and third-generation ground-based gravitational wave detec…
Exploring waveforms with non-GR deviations for extreme mass-ratio inspirals
Shailesh Kumar, Rishabh Kumar Singh, Abhishek Chowdhuri +1
The fundamental process of detecting and examining the polarization modes of gravitational waves plays a pivotal role in enhancing our grasp on the precise mechanisms behind their…
Prospects of detecting deviations to Kerr geometry with radiation reaction effects in EMRIs
Abhishek Chowdhuri, Arpan Bhattacharyya, Shailesh Kumar
Direct detection of gravitational waves and binary black hole mergers have proven to be remarkable investigations of general relativity. In order to have a definitive answer as to…
