Code — Dan Wilkins

As part of my research, I have written a range of software and computer codes, from the numerical simulation of light propagation around black holes to novel X-ray data analysis and modelling routines. Some elements of the code I have written are available on GitHub and may be used freely (though please cite the original publications when doing so). CUDAKerr is a general relativistic ray tracing simulation package for simulating the propagation of light around black holes using GPUs. These tools are designed to simulate the illumination of accretion discs around black holes by the corona as well as the observation of the disc reflection and corona by a distant observer. CUDAKerr can generate ray traced images and movies of the inner regions of the accretion flow in addition to X-ray spectral and timing data products. The ray tracing calculations are carried out on GPUs for rapid parallel computation, using the NVIDIA CUDA framework and the code is written in C++. Paper: Wilkins & Fabia
