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…
Blinded Mock Data Challenge: Is the Spectral Siren Technique Robust for Measuring the Hubble Constant?
Christos Karathanasis, Suvodip Mukherjee, Lalit Pathak +5
The measurement of the Hubble constant from gravitational wave (GW) sources is one of the independent avenues to shed light on the Hubble tension, which is associated with about an…
The First Upper Bound on the Nano-Hertz Gravitational Waves and Galaxy Cross-Correlation signal using 15-year NANOGrav Data and DESI Galaxy Survey
Mohit Raj Sah, Suvodip Mukherjee
The recent detection of a common-spectrum stochastic signal by multiple pulsar timing array (PTA) collaborations has provided tentative evidence for a nanohertz (nHz) stochastic gr…
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…
Binary Black Hole Phase Space Discovers the Signature of Pair Instability Supernovae Mass Gap
Samsuzzaman Afroz, Suvodip Mukherjee
The rapidly expanding catalog of gravitational-wave detections provides a powerful probe of the formation history of compact binaries across cosmic time. In this work, we extend th…
The Non Parametric Reconstruction of Binary Black Hole Mass Evolution from GWTC-4.0 Gravitational Wave Catalog
Samsuzzaman Afroz, Suvodip Mukherjee
The distribution of binary black hole (BBH) masses and its evolution with redshift provide key insights into the different formation channels of compact objects and their dependenc…
