Chemical modelling of interstellar MgS
M. Rey-Montejo, I. Jimenez-Serra, T. Millar +8
The detection of magnesium sulphide (MgS) and sodium sulphide (NaS) towards the Galactic Center molecular cloud G+0.693 constitutes the first detection of metal sulphides in the in…
High C/C isotopic ratios toward G+0.693-0.027: evidence for gas inflow to the Central Molecular Zone
L. Colzi, O. Sipilä, I. Jiménez-Serra +4
Isotopic ratios are key tracers of Galactic chemical evolution because different isotopes are synthesized through distinct stellar nucleosynthesis processes. While the C/$^{…
The Galactic Centre G+0.633-0.0604 molecular cloud: a new astrochemical gold mine. I. Gas physical properties
D. San Andrés, L. Colzi, V. M. Rivilla +4
In the Central Molecular Zone (CMZ), shocks play a key role in triggering star formation and driving chemical enrichment. The Sgr B2 complex is a prime template, hosting massive pr…
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…
Interstellar stereoisomerism
VÃctor M. Rivilla, Miguel Sanz-Novo, David San Andrés
The increasing detection of new molecules in the interstellar medium (ISM) shows that stereoisomerism is a fundamental contributor to interstellar molecular complexity. This work p…
