A Simple Ray Acceleration Structure for Non-LTE Radiative Transfer
Christopher M. J. Osborne
We present a novel ray acceleration structure for radiative transfer outside of local thermodynamic equilibrium (non-LTE), leveraging techniques from computer graphics to improve c…

Radiance Cascades: A Novel High-Resolution Formal Solution for Multidimensional Non-LTE Radiative Transfer
Christopher M. J. Osborne, Alexander Sannikov
Non-LTE radiative transfer is a key tool for modern astrophysics: it is the means by which many key synthetic observables are produced, thus connecting simulations and observations…
