Amides, such as urea, are key molecules in prebiotic chemistry because they possess the C-N bond, which is also found in amino acids and nucleobases. Urea has been detected in a few sources in the interstellar medium, raising questions about its synthesis. We...

Our latest research focuses on the analysis of an unusual grazing meteor, FH1, detected by the Finnish Fireball Network in October 2022. The meteoroid, with cm-sized dimensions, exhibited an inbound hyperbolic orbit and asteroidal consistency. Our findings suggest...

Atomic carbon gets chemisorbed with a water molecule when lands on water ice surfaces. The formed species can easily react with open-shell species, opening new synthetic paths towards forming interstellar complex organic molecules. The reactivity of interstellar...

Thanks to their acid-bases features, silicate surfaces can efficiently activate the chemical bonds of HCN and favor the formation of nucleophilic CN- species, hence triggering the prebiotic polymerization of HCN to nucleobases in astronomical environments. Hydrogen...

The focus is on acetaldehyde formation on the surface of a H2O:CO dirty ice, through the reaction of CH3 with an icy CO molecule of the surface, followed by a hydrogenation of the acetyl so formed. We suggest that this path is not the most favourable one, and gas...

Periodic quantum mechanical simulations shed light on the reactive adsorption of water on low stable surfaces of Schreibersite (Fe2NiP), which give rise to the transformation of surface phosphide in phosphite and phosphate forms. Phosphorus (P) is a fundamental...
