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…
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…
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…
