Arminia is a 3D website with educational and gaming elements. It explores the geometry of the unified field and the geometry of the 13 Information Systems of the Fruit of Life.

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

AGN SED model based off AGNSED (Kubota & Done 2018), but taking into account full GR ray tracing. These relativistic correction are calculated by doing the convolution with the relativistic transfer code KYCONV (Dovciak, Karas & Yaqoob 2004) at each radial annulus

A CPU/GPU Accelerated Multi-dimensional Magnetohydrodynamics Code

This is a repository of Mathematica notebooks created during my MSci thesis research at University College London. My research is largely focused on petrov classifications of vacuum and electro-vacuum black hole spacetimes as well as the geodesic motion of particles in these spacetimes. This work is supervised by Dr. Betti Hartmann
