Biases in Ringdown Tests of General Relativity from Gravitational-Wave Microlensing
Sreelakshmi Mundakkal Dasan, Anuj Mishra, Apratim Ganguly
Gravitational-wave (GW) ringdown signals provide a powerful probe of the strong-field regime of general relativity (GR) through black hole spectroscopy and tests of the Kerr hypoth…
Impact of the Host Galaxy on the Search for Gravitational-Wave Microlensing by Compact Objects
Uddeepta Deka, Apratim Ganguly, Soham Bhattacharyya +1
Gravitational-wave (GW) microlensing occurs when an intervening compact object causes diffraction of the GW, imprinting characteristic frequency-dependent modulations on the observ…
Biases in Tests of General Relativity from Microlensed Gravitational-Wave Signals
Anirban Kopty, Apratim Ganguly, N. V. Krishnendu +1
Gravitational-wave (GW) observations of compact binary mergers enable precision tests of general relativity (GR) in the strong-field regime, but their reliability depends on accura…
Higher Lovelock Curvature Terms Favor Local Nakedness in Dust Collapse
Apratim Ganguly, Radouane Gannouji, Akshay Kumar
We show that higher-curvature Lovelock terms do not restore local cosmic censorship in spherical dust collapse, but instead promote the local visibility of central shell-focusing s…
Neutron stars in Poincaré gauge gravity with quadratic torsion
Chaitanya Vashistha, Radouane Gannouji, Apratim Ganguly
We study static neutron stars in an algebraic sector of Poincaré gauge gravity with parity-even and parity-odd quadratic torsion invariants. Since torsion is non-propagating, the c…
Oppenheimer-Snyder Collapse in f(R) Gravity : Stalemate or Resolution?
Soumya Chakrabarti, Apratim Ganguly, Radouane Gannouji +1
We study the Oppenheimer--Snyder (OS) collapse problem in metric gravity by matching a homogeneous dust Friedmann--Lemaître--Robertson--Walker (FLRW) interior to a generaliz…
Can Eccentric Binary Black Hole Signals Mimic Gravitational-Wave Microlensing?
Anuj Mishra, Apratim Ganguly
Gravitational lensing in the wave-optics regime imprints characteristic frequency-dependent amplitude and phase modulations on gravitational-wave (GW) signals, yet to be detected b…
Comprehensive analysis of time-domain overlapping gravitational wave transients: A Lensing Study
Nishkal Rao, Anuj Mishra, Apratim Ganguly +1
Next-generation GW detectors will produce a high rate of temporally overlapping signals from unrelated compact binary coalescences. Such overlaps can bias parameter estimation (PE)…
