jaxpe Parameter Estimation Suite
Frequency-Domain IMRPhenomD Injection Recovery
This document summarizes the results of running the fully autonomous jaxpe sampler suite across 5 synthetic gravitational-wave injections based on parameters of prominent GWTC events.
The inference pipeline utilized a zero-noise realization with advanced LIGO Zero-detuning high-power curves, integrated with our global-local normalizing flow Metropolis-Hastings kernel.
