The Galactic centre G+0.633-0.0604 molecular cloud: A new astrochemical gold mine: II. Chemical richness
D. San Andrés, V. M. Rivilla, L. Colzi +4
In recent years, the inventory of interstellar molecules has rapidly grown, yet detections of complex species are confined to a few chemically rich sources, raising the question of…
The Galactic Centre G+0.633-0.0604 Molecular Cloud: A New Gold Mine for Astrochemistry
D. San Andrés, V. M. Rivilla, L. Colzi +4
Astrochemistry is living a golden age, with more than a quarter of the ~350 molecules in the current interstellar census having been detected over the last three years. One of the…
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…
Unveiling the 3D structure of the central molecular zone from stellar kinematics and photometry: The 50 and 20 km/s clouds
Francisco Nogueras-Lara, Ashley T. Barnes, Jonathan D. Henshaw +25
The central molecular zone (CMZ), surrounding the Galactic centre, is the largest reservoir of dense molecular gas in the Galaxy. Despite its relative proximity, the 3D structure o…
The role of supernova remnants for the emergence of pre-biotic chemistry in molecular clouds
Giuliana Cosentino, Izaskun Jiménez-Serra, Laura Colzi +11
There is growing evidence that the Sun might have formed within a nebula impacted by at least one SNR. In this scenario, ejecta and shocks from SNRs may have provided the elements…
A deep ALMA Band 3 survey of HDFS/MUSE3D: Survey description and initial results
Hugo Messias, Laura Gomez, Harold Francke +7
(abridged) After more than 10yr of ALMA operations, the community interest in conducting deep, extra-galactic, millimetre surveys resulted in varying strategic compromises between…
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…
Nonthermal Pressures: Key to Energy Balance and Structure Formation Near Sgr A* in the Milky Way
Farideh Mazoochi, Fatemeh S. Tabatabaei, Ashley T. Barnes +14
The circumnuclear region of the Galactic Center offers a unique laboratory to study energy balance and structure formation around Sgr A. This work investigates thermal and n…
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,…
Chemical templates of the Central Molecular Zone. Shock and protostellar object signatures under Galactic Center conditions
Katarzyna M. Dutkowska, Gijs Vermariën, Serena Viti +21
(Abridged) The Central Molecular Zone (CMZ) of the Milky Way exhibits extreme conditions, including high gas densities, elevated temperatures, enhanced cosmic-ray ionization rates,…
Circum-nuclear eccentric gas flow in the Galactic Center revealed by ALMA CMZ Exploration Survey (ACES)
Yoshiaki Sofue, Tomoharu Oka, Steven N. Longmore +41
We analyze the CS (J=2-1) line cube from the internal data release obtained by the large-scale program "ALMA CMZ Exploration Survey (ACES)" to investigate the kinematic structure o…
Decoding the molecular torus of NGC 1068: Insights into its structure and kinematics from high-resolution ALMA observations
V. Gámez Rosas, P. van der Werf, J. F. Gallimore +12
We dissect the kinematics and morphology of the molecular gas within the near-nuclear region of NGC 1068 to understand the mechanisms in the central AGN that might be fueling it, a…
Complex Organic Molecules towards the central molecular zone of NGC 253
M. Bouvier, S. Viti, J. G. Mangum +9
Interstellar complex organic molecules (iCOMs) may have a link to prebiotic species, key building blocks for life. In Galactic star-forming (SF) regions, spatial variations of iCOM…
