Ethanol (CHCHOH) is a relatively common molecule, often found in star-forming regions. Recent studies suggest that it could be a parent molecule of several so-called interstellar complex organic molecules (iCOMs). [...]

9 p, 1.7 MB Does processing or formation of water ice mantles affect the capacity of nanosilicates to be the source of anomalous microwave emission? / Mariñoso Guiu, Joan (Universitat de Barcelona. Departament de Ciència de Materials i Química Física) ; Ferrero, Stefano (Universitat Autònoma de Barcelona. Departament de Química) ; Macià Escatllar, Antonio (Universitat de Barcelona. 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. [...]

10 p, 1.2 MB Formation of interstellar silicate dust via nanocluster aggregation : Insights from quantum chemistry simulations / Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Bromley, Stefan (Universitat de Barcelona. Departament de Química Física)
The issue of formation of dust grains in the interstellar medium is still a matter of debate. One of the most developed proposals suggests that atomic and heteromolecular seeds bind together to initiate a nucleation process leading to the formation of nanostructures resembling very small grain components. [...]

10 p, 3.9 MB Interaction of HCO+ cations with interstellar negative frains. Quantum chemical investigation and astrophysical implications / Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química) ; Ceccarelli, Cecilia (Centre National de la Recherche Scientifique. Université Grenoble Alpes. Institut de Planétologie et d'Astrophysique de Grenoble) ; Balucani, Nadia (Università degli Studi di Perugia. Dipartimento di Chimica, Biologia e Biotecnologie) ; Ugliengo, Piero (Università degli Studi di Torino. Dipartimento di Chimica and Nanostructured Interfaces and Surfaces Centre)
In cold galactic molecular clouds, dust grains are coated by icy mantles and are prevalently charged negatively, because of the capture of the electrons in the gas. The interaction of the charged grains with gaseous cations is known to neutralize them. [...]

12 p, 1.6 MB An Ab Initio Computational Study of Binding Energies of Interstellar Complex Organic Molecules on Crystalline Water Ice Surface Models / Kakkar, Harjasnoor (Universitat Autònoma de Barcelona. Departament de Química) ; Martínez-Bachs, Berta (Universitat Autònoma de Barcelona. Departament de Química) ; Rimola, Albert (Universitat Autònoma de Barcelona. Departament de Química)
The interstellar medium is extremely heterogeneous in terms of physical environments and chemical composition. Spectroscopic observations in the recent decades have revealed the presence of gaseous material and dust grains covered in ices predominantly of water in interstellar clouds, the interplay of which may elucidate the existence of more than 250 molecular species.

375 p, 14.2 MB Surface chemistry of molecules of astrophysical interest : theory and simulations / Enrique-Romero, Joan ; Ceccarelli, Cecilia, dir. ; Rimola, Albert, dir.
En aquesta tesi he investigat alguns dels punts crítics cap a la formació d'iCOMs en la pols gelada interestel·lar. Concretament, he abordat el problema de la síntesi d'iCOMs en les superfícies dels grans de pols interestel·lar des d'un punt de vista teòric amb càlculs de química quàntica. [...]
En esta tesis he investigado algunos de los puntos críticos acerca de la formación de iCOMs en el polvo helado interestelar. En particular, he abordado el problema de la síntesis de iCOMs en las superficies de los granos de polvo interestelar desde un punto de vista teórico con cálculos de química cuántica. [...]
In this thesis I have investigated some of the critical points towards the formation of iCOMs on interstellar icy dust. In particular I have tackled the problem of the synthesis of iCOMs on the surfaces of interstellar dust grains from a theoretical point of view with quantum chemistry calculations. [...]
