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. [...]
