Research line briefing: this research line addresses the chemical complexity in space through multi and interdisciplinary frontier studies in the circumstellar envelopes of asymptotic giant branch stars (AGBs), supergiants and other evolved stars, cold molecular clouds and cold prestellar cores. We aim to identify key topics in these areas like dust grain formation, carbon, oxygen, silicon and nitrogen chemistry, deuteration, molecular tracers of shocks and water abundance. We address these science topics through ground-based multi-wavelength observations (radio with the Yebes Observatory; mm and submm with the ALMA interferometer and IRAM radio telescope; mid-infrared with the IRTF facility and optical with CAHA/CARMENES). These observations are complemented with space missions (data archives from ISO, Herschel) and airborne observatories (SOFIA in the mid-infrared). Finally, the line benefits from outstanding beyond-the-state-of-the-art laboratory experiments (GACELA under our leading ERC NANOCOSMOS project) to characterize molecules of astrophysical interest in order to search for them in Space and to study cold plasmas.

Associated members: Prof. Alfredo Aguado (head of Unidad Asociada de Química Física Aplicada, UAM), Dr. Cristina Sanz (UAM), Dr. Pablo del Mazo (UAM) and Dr. Susana G. Carrasco (USAL).

Research line briefing: this research line addresses the calculations of reactive collision and photodissociation rate coefficients to incorporate them into chemical models in order to derive molecular abundances in different astrophysical environments. Full quantum calculations are applied to systems formed by 3 or 4 atoms, while classical, semi-classical and statistical methods are used for far complex systems by including transitions between electronic states that are close in energy. New methods are in continuous development boosted by exciting astronomical results.
