ARTS, the atmospheric radiative transfer simulator
Journal of Quantitative Spectroscopy and Radiative Transfer, 2005 Abstract ARTS is a modular program that simulates atmospheric radiative transfer. The paper describes ARTS version 1.0, which is applicable in the absence of scattering. An overview over all major parts of the model is given: calculation of absorption coefficients, the radiative transfer itself, and the calculation of Jacobians.

CFD prediction of coupled radiation heat transfer and soot production in turbulent flames [PDF]
, 1996 The mechanisms governing the formation and destruction of soot in turbulent combustion are intimately coupled to thermal radiation due to the strong dependence of sooting processes and radiative loss on temperature.

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 including late-type galaxies and dusty tori.

Optimizing the Resolution of Hydrodynamic Simulations for MCRaT Radiative Transfer Calculations
The Astrophysical Journal, 2023 Despite their discovery about half a century ago, the gamma-ray burst (GRB) prompt emission mechanism is still not well understood. Theoretical modeling of the prompt emission has advanced considerably due to new computational tools and techniques.

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

The Mass Fractionation of Helium in the Escaping Atmosphere of HD 209458b
The Astrophysical Journal, 2023 The absorption signals of metastable He in HD 209458b and several other exoplanets can be explained via an escaping atmosphere model with a subsolar He/H ratio. The low abundance of helium can be a result of planet formation if there is a small amount of

Interference-exact radiative transfer simulations: intracavity transport effects [PDF]
2018 International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD), 2018 Electroluminescent (EL) cooling of semiconductors has received increasing attention in recent years. To optimize the performance of devices intended for EL cooling, special care is needed in minimizing electrical losses resulting from e.g. potential barriers, and optical losses resulting from e.g. parasitic absorption.

Distribution and Kinematics of H i through Raman He ii Spectroscopy of NGC 6302
The Astrophysical Journal, 2023 The young planetary nebula NGC 6302 is known to exhibit Raman-scattered He ii features at 6545 Å and 4851 Å. These features are formed through inelastic scattering of He ii λλ 1025 and 972 with hydrogen atoms in the ground state, for which the cross ...
