Paradigmatic examples for testing models of optical light polarization by spheroidal dust
C. Peest, R. Siebenmorgen, F. Heymann +2
We present a general framework on how the polarization of radiation due to scattering, dichroic extinction, and birefringence of aligned spheroidal dust grains can be implemented a…
Machine Learning-Assisted Anomaly Detection in Maritime Navigation Using AIS Data
Sandeep Kumar Singh, Frank Heymann
The automatic identification system (AIS) reports vessels' static and dynamic information, which are essential for maritime traffic situation awareness. However, AIS transponders c…
Self-consistent 2-phase AGN torus models: SED library for observers
Ralf Siebenmorgen, Frank Heymann, Andreas Efstathiou
We assume that dust near active galactic nuclei (AGN) is distributed in a torus-like geometry, which may be described by a clumpy medium or a homogeneous disk or as a combination o…
GPU-based Monte Carlo dust radiative transfer scheme applied to AGN
Frank Heymann, Ralf Siebenmorgen
A three dimensional parallel Monte Carlo (MC) dust radiative transfer code is presented. To overcome the huge computing time requirements of MC treatments, the computational power…
PAH in three dimensional Monte Carlo radiativtive transfer
Ralf Siebenmorgen, Frank Heymann, Endrik Krügel
We present a Monte Carlo (MC) radiative transfer code for complex three dimensional dust distributions and include transiently heated PAH. The correctness of the code is confirmed…
Shadows, gaps, and ring-like structures in protoplanetary disks
Ralf Siebenmorgen, Frank Heymann
We study the structure of passively heated disks around T Tauri and Herbig Ae stars, and present a vectorized Monte Carlo dust radiative transfer model of protoplanetary disks. The…
