Intrinsic Thickness of Black Hole Photon Rings: Evidence for Scale Separation and Transfer Factor K

This repository contains the reproducible material associated with the paper: "Intrinsic Thickness of Black Hole Photon Rings: Evidence for Scale Separation and Transfer Factor K". The work introduces a local radial coordinate to separate geometric broadening from intrinsic radial structure, leading to the extraction of an intrinsic thickness significantly smaller than the observed photon ring width. The package includes the manuscript (PDF), figures, and core analysis scripts required to reproduce the main results.
