Methanimine as a sink in the HCN and HNC solid state hydrogenation network
Joan Enrique-Romero, Thanja Lamberts
We aim to provide a systematic and quantitative description of the hydrogenation network connecting HCN and HNC to methylamine on interstellar water ices, while identifying dominan…
A sensitivity analysis of interstellar ice chemistry in astrochemical models
Tobias M. Dijkhuis, Thanja Lamberts, Serena Viti +1
Astrochemical models are essential to bridge the gap between the timescales of reactions, experiments, and observations. Ice chemistry in these models experiences a large computati…
Chemical templates of the Central Molecular Zone. Shock and protostellar object signatures under Galactic Center conditions
Katarzyna M. Dutkowska, Gijs Vermariën, Serena Viti +21
(Abridged) The Central Molecular Zone (CMZ) of the Milky Way exhibits extreme conditions, including high gas densities, elevated temperatures, enhanced cosmic-ray ionization rates,…
Interstellar Chemistry of CN Radicals on Ices: The formation of CH3CN and CH3NC and potential connection to acetamide
Joan Enrique-Romero, Thanja Lamberts
Context. Among the most significant chemical functional groups of interstellar molecules are the class of nitriles, which are proposed as key prebiotic molecules due to their chemi…
Toward Unraveling Cyanopolyyne Surface Chemistry: A Preview on Isolated Systems From HC_{3}N to Ethyl Cyanide and Propylamine
Marten T. Raaphorst, Joan Enrique-Romero, Thanja Lamberts
Cyanopolyynes, a family of nitrogen containing carbon chains, are common in the interstellar medium and possibly form the backbone of species relevant to prebiotic chemistry. Follo…
Hydrogenation of HOCO and formation of interstellar CO: A not so straightforward relation
Germán Molpeceres, Joan Enrique-Romero, Atsuki Ishibashi +5
Carbon dioxide (CO) is one of the most important interstellar molecules. While it is considered that it forms on the surface of interstellar dust grains, the exact contribution…
