Model-Independent Search Discards Faint Lensed-Pairs of Gravitational Wave Events in the Sub-Threshold Candidates of GWTC-4
Aniruddha Chakraborty, Suvodip Mukherjee
Gravitational lensing of gravitational waves (GWs) can produce multiple images in the geometric optics limit. These lensed GW images arrive at different times, are amplified by dif…
Agnostically decoding gravitational wave model deficiencies in GWTC-3
Guillaume Dideron, Suvodip Mukherjee, Luis Lehner
Gravitational Wave (GW) data bring an exceptional avenue to test the underlying models of coalescing compact objects. In the regime of strong gravity and high curvature, they allow…
The First Model-Independent Upper Bound on Micro-lensing Signature of the Highest Mass Binary Black Hole Event GW231123
Aniruddha Chakraborty, Suvodip Mukherjee
The recently discovered gravitational wave event, GW231123, is the most massive binary black hole merger detected to date. The inferred source masses of the event fall within the p…
Discovering the Dispersion of Gravitational Waves using Multi-Band Observation including Deci-Hertz: A Unique Probe to Cosmic Acceleration
Adith Praveen, Panchajanya Dey, Suvodip Mukherjee
The dispersion in the speed of gravitational waves is a novel way to test the general theory of relativity and understand whether the origin of cosmic acceleration is due to any al…
