When Two Worlds Collide: How Collisions Between Silicate and Carbonaceous Nanograins can Drive Complex Chemistry
Alexandros Kyriazis, Albert Rimola, Stefan T. Bromley
Our overall objective is to determine how collision velocity governs the interactions between silicate and carbonaceous nanograins. We aim to: i) identify collisional regimes capab…
Is cosmic dust porous?
Alexey Potapov, Martin R. S. McCoustra, Ryo Tazaki +4
There is a long-standing discussion in the astrophysical/astrochemical community as to the structure and morphology of dust grains in various astrophysical environments (e.g., inte…
The role of the pre-exponential factor on temperature programmed desorption spectra: A computational study of frozen species on interstellar icy grain mantles
S. Pantaleone, L. Tinacci, V. Bariosco +3
Temperature programmed desorption (TPD) is a well-known technique to study gas-surface processes, and it is characterized by two main quantities: the adsorbate binding energy and t…
Formation of the glycine isomer glycolamide (NHC(O)CHOH) on the surfaces of interstellar ice grains: Insights from atomistic simulations
Jessica Perrero, Silvia Alessandrini, Hexu Ye +2
Syn-glycolamide, a glycine isomer, has recently been detected in the G+0.693-0.027 molecular cloud. Investigations on its formation in the interstellar medium could offer insights…
Single-atom catalysis in space: Computational exploration of Fischer Tropsch reactions in astrophysical environments
Gerard Pareras, Victoria Cabedo, Martin McCoustra +1
Gas-phase chemistry at extreme conditions (low densities and temperatures) is difficult, so the presence of interstellar grains is especially important for the synthesis of molecul…
