Here we introduce the interstellar dust modelling framework THEMIS (The Heterogeneous
dust Evolution Model for Interstellar Solids), which takes a global view of dust and its …

The Planck and Herschel missions are currently measuring the far-infrared to millimeter
emission of dust, which combined with existing IR data, will for the first time provide the full …

This review paper provides an overview over model geometries for computing light
scattering by small particles. The emphasis is on atmospheric optics, although much of this …

The review contains an analysis of the observed and model curves of the interstellar
extinction and polarization. The observations mainly give information on dust in diffuse and …

Chirality is one of the most prominent and intriguing aspects of nature, from spiral galaxies
down to aminoacids. Despite the wide range of living and non-living, natural and artificial …

Aims. We explore the relation between the charge state of polycyclic aromatic hydrocarbons
(PAHs) and the extinction curve morphology. Methods. We fit extinction curves with a dust …

Optical tweezers are powerful tools based on focused laser beams. They are able to trap,
manipulate, and investigate a wide range of microscopic and nanoscopic particles in …

We extend and investigate the spheroidal model of interstellar dust grains used to
simultaneously interpret the observed interstellar extinction and polarization curves. We …

We demonstrate optical trapping of plasmonic silica-gold mesocapsules and their use as
local SERS probes in Raman tweezers. These novel hybrid dielectric-metal particles …

We investigate the remarkable apparent variety of galactic extinction curves by modeling
extinction profiles with core-mantle grains and a collection of single polycyclic aromatic …
