Blacklight: A General-Relativistic Ray-Tracing and Analysis Tool

Understand

We describe the Blacklight code, intended for post-processing general-relativistic magnetohydrodynamic simulation data.

• Beyond polarized ray tracing of synchrotron radiation, it can produce a number of outputs that aid in analyzing data sets, such as maps of auxiliary quantities and false-color renderings.
• Additional features include support for adaptive mesh refinement input, slow-light calculations, and adaptive ray tracing.
• The code is written with ease of use, readability, and transparency as primary objectives, while it still achieves high performance.
