ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions -- XIX. The origin of SiO emission
Rong Liu, Tie Liu, Izaskun Jiménez-Serra +23
The production of silicon monoxide (SiO) can be considered as a fingerprint of shock interaction. In this work, we use high-sensitivity observations of the SiO (2-1) and HCO…
First detection of a deuterated molecule in a starburst environment within NGC 253
J. Butterworth, S. Martín, V. M. Rivilla +7
Deuterium was primarily created during the Big Bang Nucleosynthesis (BBN). This fact, alongside its fractionation reactions resulting in enhanced abundances of deuterated molecules…
Components of star formation in NGC 253 : Non-negative Matrix Factorization Analysis with the ALCHEMI integrated intensity images
Ryo Kishikawa, Nanase Harada, Toshiki Saito +12
It is essential to examine the physical or chemical properties of molecular gas in starburst galaxies to reveal the underlying mechanisms characterizing starbursts. We used non-neg…
Disruption of a massive molecular cloud by a supernova in the Galactic Centre: Initial results from the ACES project
M. Nonhebel, A. T. Barnes, K. Immer +33
The Milky Way's Central Molecular Zone (CMZ) differs dramatically from our local solar neighbourhood, both in the extreme interstellar medium conditions it exhibits (e.g. high gas,…
A new measurement of the Galactic C/C gradient from sensitive HCO absorption observations
Gan Luo, Laura Colzi, Tie Liu +4
We present a new constraint on the Galactic C/C gradient with sensitive HCO absorption observations against strong continuum sources. The new measurements suffer…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. IV. ALMA observations of organic species at Galactocentric radius ~23 kpc
F. Fontani, G. Vermariën, S. Viti +7
Single-dish observations suggest that the abundances of organic species in star-forming regions of the outer Galaxy, characterised by sub-Solar metallicities, are comparable to tho…
Neural Network Constraints on the Cosmic-Ray Ionization Rate and Other Physical Conditions in NGC 253 with ALCHEMI Measurements of HCN and HNC
Erica Behrens, Jeffrey G. Mangum, Serena Viti +15
We use a neural network model and ALMA observations of HCN and HNC to constrain the physical conditions, most notably the cosmic-ray ionization rate (CRIR, zeta), in the Central Mo…
Astrochemistry on Galactic scales
L. Colzi, V. M. Rivilla, M. T. Beltrán +3
The increasing number of observations towards different environments in the Milky Way, as well as theoretical and experimental works, are improving our knowledge of the astrochemic…
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…
Discovery of MgS and NaS in the Interstellar Medium and tentative detection of CaO
M. Rey-Montejo, I. Jimenez-Serra, J. Martin-Pintado +12
We report the first detection of the metal-bearing molecules sodium sulfide (NaS) and magnesium sulfide (MgS) and the tentative detection of calcium monoxide (CaO) in the interstel…
An ALCHEMI inspection of sulphur-bearing species towards the central molecular zone of NGC 253
M. Bouvier, S. Viti, E. Behrens +19
Sulphur-bearing species are detected in various environments within Galactic star-forming regions and are particularly abundant in the gas phase of outflows and shocks, and photo-d…
A broad linewidth, compact, millimeter-bright molecular emission line source near the Galactic Center
Adam Ginsburg, John Bally, Ashley T. Barnes +37
A compact source, G0.02467-0.0727, was detected in ALMA \threemm observations in continuum and very broad line emission. The continuum emission has a spectral index ,…
The GUAPOS project. V: The chemical ingredients of a massive stellar protocluster in the making
Á. López-Gallifa, V. M. Rivilla, M. T. Beltrán +9
Most stars, including the Sun, are born in rich stellar clusters containing massive stars. Therefore, the study of the chemical reservoir of massive star-forming regions is crucial…
The Wide-field Spectroscopic Telescope (WST) Science White Paper
Vincenzo Mainieri, Richard I. Anderson, Jarle Brinchmann +214
The Wide-field Spectroscopic Telescope (WST) is proposed as a new facility dedicated to the efficient delivery of spectroscopic surveys. This white paper summarises the initial con…
First detection in space of the high-energy isomer of cyanomethanimine: H2CNCN

We report the first detection in the interstellar medium of -cyanomethanimine (HCNCN), the stable dimer of HCN of highest energy, and the most complex organic molecule ident…
Physical Properties of the Southwest Outflow Streamer in the Starburst Galaxy NGC 253 with ALCHEMI
Min Bao, Nanase Harada, Kotaro Kohno +19
The physical properties of galactic molecular outflows are important as they could constrain outflow formation mechanisms. We study the properties of the southwest (SW) outflow str…
