Code for: Gravitational-Wave Echo Predictions for Reflective Horizon-Scale Structure: A Catalogue from GWTC Posterior Samples

This repository contains the source code used to reproduce the results presented in the manuscript "Gravitational-Wave Echo Predictions for Reflective Horizon-Scale Structure: A Catalogue from GWTC Posterior Samples." The software computes gravitational-wave echo time delays for compact objects with reflective horizon-scale structure using publicly available GWTC posterior samples. It includes implementations of the Kerr echo-delay calculations, numerical simulations, event catalogue generation, and figure-production scripts used in the manuscript. Contents Kerr echo-delay calculation routines Echo simulation programs GWTC catalogue generation scripts Figure-generation scripts Build scripts used to reproduce the manuscript figures The calculations use publicly available gravitational-wave posterior samples from the Gravitational Wave Open Science Center (GWOSC). This repository is provided to ensure the reproducibility of all numerical results presented in the accompanying paper.
