Despite the generally hostile nature of the environments involved, chemistry does occur in
space. Molecules are seen in environments that span a wide range of physical and chemical …

The gas-phase reaction networks are the backbone of astrochemical models. However, due
to their complexity and nonlinear impact on the astrochemical modeling, they can be the first …

Context. The simultaneous detection of organic molecules of the form C 2 H n O, such as
ketene (CH 2 CO), acetaldehyde (CH 3 CHO), and ethanol (CH 3 CH 2 OH), toward early …

Unravelling the generation of complex organic molecules (COMs) on interstellar
nanoparticles (grains) is essential in establishing predictive astrochemical reaction networks …

Context. Reliable, directly measured optical properties of astrophysical ice analogues in the
infrared and terahertz (THz) range are missing from the literature. These parameters are of …

Conspectus Laboratory-based experimental astrochemistry regularly entails simulation of
astrophysical environments whereby low-temperature condensed ices are exposed to …

The crystallinity and morphology of solid carbon monoxide (CO) on icy interstellar grains
were examined by observing the deposition, crystallization, and UV and electrons irradiation …

The motivation to study experimentally CO ice under mimicked interstellar conditions is
supported by the large CO gas abundances and ubiquitous presence of CO in icy grain …

We present a dedicated experimental study of microscopic mechanisms controlling
radiolysis and sputtering of astrophysical ices upon bombardment by cosmic-ray ions. Such …

Context. Cosmic rays and solar energetic particles induce changes in the composition of
compounds frozen onto dust grains in the interstellar medium (ISM), in comets, and on the …
