Accounting for the Known Unknowns: A Parametric Framework to Incorporate Systematic Waveform Errors in Gravitational-Wave Parameter Estimation
Sumit Kumar, Max Melching, Frank Ohme
The PE for GW merger events relies on a waveform model calibrated using numerical simulations. Within the Bayesian framework, this waveform model represents the GW signal produced…
Constraints on cosmologically coupled black holes from gravitational wave observations and minimal formation mass
Luca Amendola, Davi C. Rodrigues, Sumit Kumar +1
We test the possibility that the black holes (BHs) detected by LIGO-Virgo-KAGRA (LVK) may be cosmologically coupled and grow in mass proportionally to the cosmological scale factor…
Constraining mass of the graviton with GW170817
Andrey A. Shoom, Sumit Kumar, N. V. Krishnendu
We consider the massive graviton phenomenological model based on the graviton's dispersion terms included into phase of gravitational wave's waveform. Such model was already consid…
A novel ringdown amplitude-phase consistency test
Xisco Jiménez Forteza, Swetha Bhagwat, Sumit Kumar +1
The ringdown signal emitted during a binary black hole coalescence can be modeled as a linear superposition of the characteristic damped modes of the remnant black hole that get ex…
Probing Cosmology with Baryon Acoustic Oscillations using Gravitational Waves
Sumit Kumar
The third-generation (3G) gravitational wave (GW) detectors such as the Einstein telescope (ET) or Cosmic Explorer (CE) are expected to play an important role in cosmology. With th…
Parameter Estimation with Nonstationary Noise in Gravitational-wave Data
Sumit Kumar, Alexander H. Nitz, Xisco Jiménez Forteza
The sensitivity of gravitational-wave (GW) detectors is characterized by their noise curves, which determine the detector's reach and ability to measure the parameters of astrophys…
