accretion

A 2D ideal GRMHD code derived from iharm3d with fewer dependencies and better documentation

A set of codes which, using relativistic ray tracing, calculates the intensity profile of plasma being accreted onto a black hole.

Simulation of a 2 dimensional cloud of space dust

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.

Full Spectral Timing model for AGN. Calculates time-dependent SEDs, including an intrinsically variable disc (propagating fluctuations), disc reverberation, and wind re-processing

Code calculates vertical and radial structure of accretion discs around neutron stars and black holes.

A four-dimensional inhomogeneous, anisotropic Gaussian random field generator.

A scale-invariant astrophysics framework and reproducible dataset for comparing black holes across mass scales using GR-based metrics (ISCO, Kerr spin, jet power)
