Formation Of Interstellar Complex Organic Molecules On Water-rich Ices Triggered By Atomic Carbon Freezing
The reactivity of interstellar carbon atoms (C) on the water-dominated ices is one of the possible ways to form interstellar complex organic molecules (iCOMs).

Hunt For Complex Cyanides In Protostellar Ices With JWST: Tentative Detection Of CH3CN And C2H5CN
Nitrogen-bearing complex organic molecules have been commonly detected in the gas phase but not yet in interstellar ices. This has led to the long-standing question of whether these molecules form […]
