SKIRT: hybrid parallelization of radiative transfer simulations [PDF]

Astronomy and Computing, 2017
We describe the design, implementation and performance of the new hybrid parallelization scheme in our Monte Carlo radiative transfer code SKIRT, which has been used extensively for modeling the continuum radiation of dusty astrophysical systems ...

TRAPHIC - Radiative Transfer for Smoothed Particle Hydrodynamics Simulations [PDF]

Monthly Notices of the Royal Astronomical Society, 2008
We present TRAPHIC, a novel radiative transfer scheme for Smoothed Particle Hydrodynamics (SPH) simulations. TRAPHIC is designed for use in simulations exhibiting a wide dynamic range in physical length scales and containing a large number of light ...

Using 3D Voronoi grids in radiative transfer simulations [PDF]

Astronomy & Astrophysics, 2013
Probing the structure of complex astrophysical objects requires effective three-dimensional (3D) numerical simulation of the relevant radiative transfer (RT) processes. As with any numerical simulation code, the choice of an appropriate discretization is

RADAMESH: Cosmological Radiative Transfer for Adaptive Mesh Refinement Simulations

, 2010
We present a new three-dimensional radiative transfer (RT) code, RADAMESH, based on a ray-tracing, photon-conserving and adaptive (in space and time) scheme.

Advances in Simulating Radiative Transfer in Complex Environments [PDF]

Applied Sciences, 2021
Accurate simulation of radiative transfer is a very important aspect in climate modeling. For microclimate models in particular, it is not only important to simulate primary but also secondary radiative fluxes in great detail, i.e., emitted longwave and reflected shortwave radiation.

Monte Carlo simulations in anomalous radiative transfer: tutorial

Journal of the Optical Society of America A, 2022
Anomalous radiative transfer (ART) theory represents a generalization of classical radiative transfer theory. The present tutorial aims to show how Monte Carlo (MC) codes describing the transport of photons in anomalous media can be implemented. We show that the heart of the method involves suitably describing, in a “non-classical” manner, photon steps

Spherical Harmonics for the 1D Radiative Transfer Equation. I. Reflected Light

The Astrophysical Journal, 2023
A significant challenge in radiative transfer theory for atmospheres of exoplanets and brown dwarfs is the derivation of computationally efficient methods that have adequate fidelity to more precise, numerically demanding solutions.
