The transition matrix, frequently abbreviated as T-matrix, contains the complete information
in a linear approximation of how a spatially localized object scatters an incident field. The T …

We introduce Monte-Carlo-based non-local thermodynamic equilibrium (non-LTE) line
radiative transfer calculations in the three-dimensional (3D) dust radiative transfer code …

Supernova remnants (SNRs) are well-recognized dust producers, but their net dust
production rate remains elusive due to uncertainties in grain properties that propagate into …

We have developed a new method for using the observed starlight polarization and
polarized submillimeter emission to constrain the shapes and porosities of interstellar …

Context. Polarised emission from non-spherical dust grains contains information about the
alignment of these dust grains and traces the structure of the interstellar magnetic field …

Context. The Monte Carlo method is probably the most widely used approach to solve the
radiative transfer problem, especially in a general 3D geometry. The physical processes of …

The approximation of real non-spherical scatterers by spheroids is used in various
applications. It often requires fast massive calculations of the optical properties of spheroids …

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 …

The approximation of cosmic dust grains by spheroids is widely used to model their optical
properties. The spheroidal model combines relative simplicity, which in some cases makes it …

We present detection of dust polarized emission of the Crab Nebula (M 1) in the far-infrared,
from SOFIA/HAWC+ observations, at 89 and 154 µm. After removing the signal from …
