An adaptive analytical ray-tracing code to study black hole photon rings - Kerr Raytracing

Beampy is a python package - with an user interface - allowing to propagate beams in differents guides using the Beam Propagation Method (BPM)

A SageMath package to compute gravitational radiation from bodies orbiting a Kerr black hole

A Package to Compute mode functions for Kerr Black Hole Quasinormal modes, as well as their frequencies, seperation constants and more. Additionally provides an interface for cheap differentiation of such modes.

KerrP2P is a software designed for forward ray tracing in Kerr spacetime. It is specifically tailored to efficiently calculate multiple null geodesics between designated "source" and "observer" points, locate apparent positions of the corresponding images, and quantify their shapes.

Real time photon tracing -- pretty images -- of a spinning Kerr blackhole

Fast analytic raytracing around Kerr black holes

Simulation of linear and nonlinear (Raman, Kerr) coupling in few-mode fibers

This mathematica code numerically solves the Hamilton and geodesic equations in Slowly-rotating Kerr

A Package to Compute wave functions for Kerr Black Hole Quasinormal modes, as well as their frequencies, seperation constants and more. Additionally provides an interface for cheap differentiation of such modes.

Set of MATLAB formulas for computing the nonlinearity of graphene, with emphasis on the optical band (e.g., NIR) and the self-acting (Kerr-like) effect.

A physical-based accretion disk emission model coupled to the Adaptive Analytical Ray Tracing (AART) code that allows a fast parameter space exploration of black hole photon rings produced from synchrotron emission from 10 to 670 GHz.
