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…
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…
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,…
Excitation and spatial study of a prestellar cluster towards G+0.693-0.027 in the Galactic centre
L. Colzi, J. Martín-Pintado, S. Zeng +6
Star formation in the central molecular zone (CMZ) is suppressed with respect to that of the Galactic disk, and this is likely related to its high turbulent environment. This turbu…
Cloud-cloud collision as drivers of the chemical complexity in Galactic Centre molecular clouds
S. Zeng, Q. Zhang, I. Jimenez-Serra +6
G+0.693-0.03 is a quiescent molecular cloud located within the Sagittarius B2 (Sgr B2) star-forming complex. Recent spectral surveys have shown that it represents one of the most p…
Complex organic molecules in the Galactic Centre: the N-bearing family
S. Zeng, I. Jiménez-Serra, V. M. Rivilla +6
We present an unbiased spectral line survey toward the Galactic Centre (GC) quiescent giant molecular cloud (QGMC), G+0.693 using the GBT and IRAM 30 telescopes. Our study high…
