A fast machine learning tool to predict the composition of astronomical ices from infrared absorption spectra
Andrés MegÃas, Izaskun Jiménez-Serra, François Dulieu +6
Current observations taken by James Webb Space Telescope (JWST) allow us to observe the absorption features of icy mantles that cover interstellar dust grains, which are mainly com…
The GUAPOS project. VI: the chemical inventory of shocked gas
Ã. López-Gallifa, V. M. Rivilla, M. T. Beltrán +8
The study of the chemical composition of star-forming regions is key to understanding the chemical ingredients available during the formation of planetary systems. Because the chem…
Piecing together formic acid isomerism in dark clouds. Detection of cis-formic acid in TMC-1 and astrochemical modeling
G. Molpeceres, M. Agúndez, M. Mallo +6
The presence of molecular isomers in interstellar environments has become a topic of growing interest within the astrochemical community. Contrary to predictions based on thermodyn…
High-energy interstellar isomers: cis-N-methylformamide in the G+0.693-0.027 molecular cloud
S. Zeng, V. M. Rivilla, M. Sanz-Novo +8
Isomerism in complex organic molecules provides key insights into the formation mechanisms and physical conditions of the interstellar medium (ISM). Among the CHNO isomers,…
CO Depletion in Infrared Dark Clouds
G. Cosentino, J. C. Tan, C. Gainey +10
Infrared Dark Clouds (IRDCs) are cold, dense structures representative of the initial conditions of star formation. Many studies of IRDCs employ CO to investigate cloud dynamics. H…
Rotational Spectroscopy and Tentative Interstellar Detection of 3-Hydroxypropanal (HOCHCHCHO) in the G+0.693-0.027 Molecular Cloud
Zachary T. P. Fried, Roman A. Motiyenko, Miguel Sanz-Novo +12
We synthesized the astrochemically relevant molecule 3-hydroxypropanal (HOCHCHCHO) and subsequently measured and analyzed its rotational spectrum in several frequency regio…
