The carbon (3P) atom is a reactive species that, according to laboratory experiments and theoretical calculations, condensates with interstellar ice components. This fact is of uttermost importance for the chemistry in the interstellar medium (ISM) because the condensation reaction is barrierless, and the subsequent species formed are still reactive given their open-shell character.

Dipartimento di Chimica) ; Minissale, M. (Centre National de la Recherche Scientifique. Aix-Marseille University) ; Ugliengo, Piero (Università degli Studi di Torino. Dipartimento di Chimica)
Acetaldehyde is one of the most common and abundant gaseous interstellar complex organic molecules found in cold and hot regions of the molecular interstellar medium. Its presence in the gas-phase depends on the chemical formation and destruction routes, and its binding energy (BE) governs whether acetaldehyde remains frozen on to the interstellar dust grains or not.

12 p, 4.1 MB Where does the energy go during the interstellar NH3 formation on water ice? a computational study / Ferrero, Stefano (Universitat Autònoma de Barcelona. Departament de Química) ; Pantaleone, Stefano (Università degli Studi di Torino. Dipartimento di Chimica) ; Ceccarelli, Cecilia (Centre National de la Recherche Scientifique.

Departament de Química) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
In the coldest (10-20 K) regions of the interstellar medium, the icy surfaces of interstellar grains serve as solid-state supports for chemical reactions. Among their plausible roles, that of third body is advocated, in which the reaction energies of surface reactions dissipate throughout the grain, stabilizing the product. [...]

Departament de Ciència de Materials i Química Física) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Bromley, Stefan (Universitat de Barcelona. Departament de Ciència de Materials i Química Física)
Anomalous microwave emission (AME) is detected in many astrophysical environments as a foreground feature typically peaking between 20-30 GHz and extending over a 10-60 GHz range. One of the leading candidates for the source of AME is small spinning dust grains. [...]

The universe is molecularly rich, comprising from the simplest molecule (H2) to complex organic molecules (e. g. , CH3CHO and NH2CHO), some of which of biological relevance (e. g. , amino acids). This chemical richness is intimately linked to the different physical phases forming Solar-like planetary systems, in which at each phase, molecules of increasing complexity form. [...]
