Rapid inference of gravitational-wave signals in the time domain using a heterodyned likelihood
Neha Sharma, Aditya Vijaykumar, Prayush Kumar
Parameter estimation of gravitational wave signals is computationally intensive and typically requires millions of likelihood evaluations to construct posterior probability distrib…
Implications of GW241011 for rotating exotic compact objects
N. V. Krishnendu, Tamara Evstafyeva, Aditya Vijaykumar +17
A number of theoretical proposals have been made for horizonless compact objects with masses and spins similar to those of black holes. While gravitational wave signatures from the…
Inference with finite time series II: the window strikes back
Colm Talbot, Sylvia Biscoveanu, Aaron Zimmerman +9
Smooth window functions are often applied to strain data when inferring the parameters describing the astrophysical sources of gravitational-wave transients. Within the LIGO-Virgo-…
Bounds on the charge of the graviton using gravitational wave observations
Sreejith Nair, Aditya Vijaykumar, Sudipta Sarkar
If the graviton possesses a non-zero charge , gravitational waves (GW) originating from astrophysical sources would experience an additional time delay due to intergalactic ma…
Impact of higher harmonics of gravitational radiation on the population inference of binary black holes
Mukesh Kumar Singh, Shasvath J Kapadia, Aditya Vijaykumar +1
Templates modeling just the dominant mode of gravitational radiation are generally sufficient for the unbiased parameter inference of near-equal-mass compact binary mergers. Howeve…
Effect of double spin-precession and higher harmonics on spin-induced quadrupole moment measurements
Divyajyoti, N. V. Krishnendu, Muhammed Saleem +4
We investigate the prospect of performing a null test of binary black hole (BBH) nature using spin-induced quadrupole moment (SIQM) measurements. This is achieved by constraining a…
