Precision Ringdown Measurements of Binary Black Hole Remnants
Achal Kumar, Poulami Dutta Roy, Marek J. SzczepaÅczyk +2
The paper presents a precise analysis of the ringdown phase of binary black hole mergers using coherent WaveBurst reconstruction, yielding tighter constraints on the dominant quasi…

Inferring additional physics through unmodelled signal reconstructions
Rimo Das, V. Gayathri, Divyajyoti +4
Parameter estimation of gravitational wave data is often computationally expensive, requiring simplifying assumptions such as circularisation of binary orbits. Although, if include…

Gravitational Wave Detector Sensitivity to Eccentric Black Hole Mergers
Shubhagata Bhaumik, V. Gayathri, Imre Bartos +8
Orbital eccentricity in compact binary mergers carries crucial information about the binary's formation and environment. There are emerging signs that some of the mergers detected…
