CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy III. Nitrogen isotopic ratios in the outer Galaxy
L. Colzi, D. Romano, F. Fontani +6
Nitrogen isotopic ratios are a key tool for tracing Galactic stellar nucleosynthesis. We present the first study of the N/N abundance ratio in the outer regions of th…
Tracing Interstellar Heating: An ALCHEMI Measurement of the HCN Isomers in NGC 253
Erica Behrens, Jeffrey G. Mangum, Jonathan Holdship +17
We analyze HCN and HNC emission in the nearby starburst galaxy NGC 253 to investigate its effectiveness in tracing heating processes associated with star formation. This study uses…
ALCHEMI finds a "shocking" carbon footprint in the starburst galaxy NGC~253
Nanase Harada, Sergio Martin, Jeff Mangum +15
Centers of starburst galaxies may be characterized by a specific gas and ice chemistry due to their gas dynamics and the presence of various ice desorption mechanisms. This may res…
Molecular precursors of the RNA-world in space: new nitriles in the G+0.693-0.027 molecular cloud
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesus Martín-Pintado +10
Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. II. Methanol formation at low metallicity
F. Fontani, A. Schmiedeke, A. Sanchez-Monge +8
The outer Galaxy is an environment with metallicity lower than the Solar one and, because of this, the formation and survival of molecules in star-forming regions located in the in…
Energizing Star Formation: The Cosmic Ray Ionization Rate in NGC 253 Derived From ALCHEMI Measurements of HO and SO
Jonathan Holdship, Jeffrey G. Mangum, Serena Viti +16
The cosmic ray ionization rate (CRIR) is a key parameter in understanding the physical and chemical processes in the interstellar medium. Cosmic rays are a significant source of en…
Methanol masers in NGC 253 with ALCHEMI
P. K. Humire, C. Henkel, A. Hernández-Gómez +23
Context: Methanol masers of Class I (collisionally-pumped) and Class II (radiatively-pumped) have been studied in great detail in our Galaxy in a variety of astrophysical environme…
Precursors of fatty alcohols in the ISM: Discovery of n-propanol
Izaskun Jimenez-Serra, Lucas F. Rodriguez-Almeida, Jesus Martin-Pintado +12
Theories on the origins of life propose that early cell membranes were synthesized from amphiphilic molecules simpler than phospholipids such as fatty alcohols. The discovery in th…
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…
CHEMOUT: CHEMical complexity in star-forming regions of the OUTer Galaxy. I. Organic molecules and tracers of star-formation activity
F. Fontani, L. Colzi, L. Bizzocchi +8
The outer Galaxy is an environment with metallicity lower than the Solar one. Because of this, the formation and survival of molecules in star-forming regions located in the inner…
Deuterium fractionation as a multi-phase component tracer in the Galactic Centre
L. Colzi, J. Martín-Pintado, V. M. Rivilla +6
The Central Molecular Zone (CMZ) contains most of the mass of our Galaxy but its star formation rate is one order of magnitude lower than in the Galactic disc. This is likely relat…
First extragalactic detection of a phosphorus-bearing molecule with ALCHEMI: phosphorus nitride (PN)
D. Haasler, V. M. Rivilla, S. Martín +16
Phosphorus (P) is a crucial element for life given its central role in several biomolecules. P-bearing molecules have been discovered in different regions of the Milky Way, but not…
