Hybrid Scene Structuring for Accelerating 3D Radiative Transfer Simulations

open access: yesRemote Sensing, 2019
Three-dimensional (3D) radiative transfer models are the most accurate remote sensing models. However, presently the application of 3D models to heterogeneous Earth scenes is a computationally intensive task.

SKIRT: Hybrid parallelization of radiative transfer simulations [PDF]

open access: yesAstronomy 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

open access: yesThe 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.

The Mass Fractionation of Helium in the Escaping Atmosphere of HD 209458b

open access: yesThe 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

Monte Carlo simulations in anomalous radiative transfer: tutorial

open access: yesJournal 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

Interference-exact radiative transfer simulations: intracavity transport effects [PDF]

open access: yes2018 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

open access: yesThe 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 ...

A Radiative Transfer Simulator for PACE: Theory and Applications [PDF]

open access: yesFrontiers in Remote Sensing, 2022
A radiative transfer simulator was developed to compute the synthetic data of all three instruments onboard NASA’s Plankton Aerosol, Cloud, ocean Ecosystem (PACE) observatory, and at the top of the atmosphere (TOA). The instrument suite includes the ocean color instrument (OCI), the Hyper-Angular Rainbow Polarimeter 2 (HARP2), and the Spectro ...
