CHemical Evolution in MassIve star-forming COres (CHEMICO). II. Molecular ions, electron fraction, and cosmic-ray ionisation rate
F. Fontani, E. Roueff, V. M. Rivilla +5
Molecular ions are crucial in initiating and regulating the formation of molecules in the interstellar medium, and are expected to be sensitive tracers of evolution in star-forming…
Chemistry here and there: Comparison between the CMZ of the Milky Way and NGC 253
Sergio Martín, Álvaro López-Gallifa, David San Andrés +2
For decades, chemical studies in external galaxies have been limited by sensitivity, resolution, bandwidth or a combination of them. A decade of ALMA operations, made the detailed…
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…
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…
On the abiotic origin of dimethyl sulfide: discovery of DMS in the Interstellar Medium
Miguel Sanz-Novo, Víctor M. Rivilla, Christian P. Endres +14
Following the discovery of dimethyl sulfide (CHSCH, DMS) signatures in comet 67P/Churyumov-Gerasimenko, we report the first detection of this organosulfur species in the in…
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…
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…
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…
First detection in space of the high-energy isomer of cyanomethanimine: H2CNCN
David San Andrés, Víctor M. Rivilla, Laura Colzi +14
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…
Discovery of thionylimide, HNSO, in space: the first N-, S- and O-bearing interstellar molecule
Miguel Sanz-Novo, Víctor M. Rivilla, Holger S. P. Müller +12
We present the first detection in space of thionylimide (HNSO) toward the Galactic Center molecular cloud G+0.693-0.027, thanks to the superb sensitivity of an ultradeep molecular…
Interstellar detection of O-protonated carbonyl sulfide, HOCS+
Miguel Sanz-Novo, Víctor M. Rivilla, Izaskun Jiménez-Serra +12
We present the first detection in space of O-protonated carbonyl sulfide (\ch{HOCS+}), in the midst of an ultradeep molecular line survey toward the G+0.693-0.027 molecular cloud.…
First glycine isomer detected in the interstellar medium: glycolamide (NHC(O)CHOH)
Víctor M. Rivilla, Miguel Sanz-Novo, Izaskun Jiménez-Serra +13
We report the first detection in the interstellar medium of a CHON isomer: -glycolamide (NHC(O)CHOH). The exquisite sensitivity at sub-mK levels of an ultr…
Discovery of the elusive carbonic acid (HOCOOH) in space
Miguel Sanz-Novo, Víctor M. Rivilla, Izaskun Jiménez-Serra +12
After a quarter century since the detection of the last interstellar carboxylic acid, acetic acid (CHCOOH), we report the discovery of a new one, the cis-trans form of carbonic…
Precursors of the RNA-world in space: Detection of ()-1,2-ethenediol in the interstellar medium, a key intermediate in sugar formation
Víctor M. Rivilla, Laura Colzi, Izaskun Jiménez-Serra +20
We present the first detection of ()-1,2-ethenediol, (CHOH), the enol form of glycolaldehyde, in the interstellar medium towards the G+0.693-0.027 molecular cloud located in…
