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)

Fast analytic raytracing around Kerr black holes

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

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.

Jipole is a Julia-based imaging tool built on the general relativistic ray-tracing framework of ipole. Using ForwardDiff.jl, it computes intensity derivatives with respect to input parameters, enabling fast and precise gradient-based fitting of synthetic images to observational data.

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.

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

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

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.

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.

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

Simulation 3D interactive de trajectoires de particules autour d'un trou noir de Kerr

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.
