The interstellar medium is characterized by a rich and diverse chemistry. Many of its
complex organic molecules are proposed to form through radical chemistry in icy grain …

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 …

Context. High-quality vibrational spectra of solid-phase molecules in ice mixtures and for
temperatures of astrophysical relevance are needed to interpret infrared observations …

Sulfur is the tenth most abundant element in the universe and is known to play a significant
role in biological systems. Accordingly, in recent years there has been increased interest in …

Astrophysical ices are being exposed to ionizing radiation in space environments, which
trigger new reactions and desorption processes. In the lab, such processing by radiation has …

In this work, the chemical evolution of pure acetonitrile ice at 13 K irradiated with broad-band
soft X-rays (from 6 eV to 2 keV) is determined by using a computational methodology …

For the last century, the source of sulfur in Earth's very first organisms has remained a
fundamental, unsolved enigma. While sulfates and their organic derivatives with sulfur in the …

Chemical reactions and desorption processes are being triggered by incoming ionizing
radiation over astrophysical ices in cold space environments. The quantification of these …

Laboratory experiments have confirmed that the radiolytic decay rate of astrochemical ice
analogues is dependent upon the solid phase of the target ice, with some crystalline …
