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…

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…
