Magrathea-Pathfinder: A 3D adaptive-mesh code for geodesic ray tracing in -body simulations
Michel-Andrès Breton, Vincent Reverdy
We introduce Magrathea-Pathfinder, a relativistic ray-tracing framework that can reconstruct the past light cone of observers in cosmological simulations. The code directly compute…
