Detection of a four-carbon sugar in interstellar space
Izaskun Jimenez-Serra, Juan Garcia de la Concepcion, Herma M. Cuppen +19
Sugars are essential biomolecules, serving as metabolic fuels, nucleic acid backbone components, and structural or energy-storage polymers. A central question in origin-of-life res…
Aromatic rings in the Central Molecular Zone: Benzonitrile
V. M. Rivilla, D. San Andrés, M. Sanz-Novo +12
In recent years, several aromatic molecules (benzene-based rings) have been detected in the cold molecular cloud TMC-1, with its CN-derivative, benzonitrile (c-CHCN), also…
CII fine-structure line observations of the Sagittarius C Region in the Galaxy's Central Molecular Zone
DEnise Riquelme-Vasquez, Rolf Guesten, Mark R. Morris +7
Context. Sagittarius C (Sgr C) is a massive, relatively quiescent complex at the western edge of the Galaxy's Central Molecular Zone (CMZ). While the Sgr B2 region has been extensi…
A detection of sulfur-bearing cyclic hydrocarbons in space
Mitsunori Araki, Miguel Sanz-Novo, Christian P. Endres +13
Molecules harbouring sulfur are thought to have played a key role in the biological processes of life on Earth, and thus, they are of much interest when found in space. Here we rep…
Expanding the CHO Isomeric Interstellar Inventory: Discovery of Lactaldehyde and Methoxyacetaldehyde in G+0.693-0.027
M. Sanz-Novo, V. M. Rivilla, I. Jiménez-Serra +17
The tentative detection of 3-hydroxypropanal (HO(CH)C(O)H) toward the Galactic center molecular cloud G+0.693-0.027 prompts a systematic survey in this source aimed at dete…
The Emergence of Prebiotic Chemistry in the ISM
Izaskun Jimenez-Serra, Giuliana Cosentino, Francisco Montenegro-Montes +22
Contrary to popular belief, the interstellar medium (ISM) is not empty; it is filled with atoms, dust particles, and molecules. Some of these molecules may have been the very build…
