The GUAPOS project: G31.41+0.31 Unbiased ALMA sPectral Observational Survey. IV. Phosphorus-bearing molecules and their relation with shock tracers
F. Fontani, C. Mininni, M. T. Beltrán +6
The astrochemistry of the important biogenic element phosphorus (P) is still poorly understood, but observational evidence indicates that P-bearing molecules are likely associated…
Volume density structure of the NGC253 CMZ through ALCHEMI excitation analysis
Kunihiko Tanaka, Jeffrey G. Mangum, Serena Viti +21
We present a spatially-resolved excitation analysis for the central molecular zone (CMZ) of the starburst galaxy NGC 253 using the data from the ALMA Large program ALCHEMI, whereby…
Combined model for , , and spin-state chemistry in molecular clouds
O. Sipilä, L. Colzi, E. Roueff +3
We present a new gas-grain chemical model for the combined isotopic fractionation of carbon and nitrogen in molecular clouds, in which the isotope chemistry of carbon and nitrogen…
The evolution of sulphur-bearing molecules in high-mass star-forming cores
F. Fontani, E. Roueff, L. Colzi +1
To understand the chemistry of sulphur (S) in the interstellar medium, models need to be tested by observations of S-bearing molecules in different physical conditions. We analyse…
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…
The first detection of SiC in the interstellar medium
S. Massalkhi, I. Jiménez-Serra, J. Martín-Pintado +7
We report the first detection of SiC in the interstellar medium. The molecule was identified through six rotational transitions toward G\,+0.6930.027, a molecular cloud loca…
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…
The GUAPOS project:III. Characterization of the O- and N-bearing complex organic molecules content and search for chemical differentiation
C. Mininni, M. T. Beltrán, L. Colzi +8
The G31.41+0.31 Unbiased ALMA sPectral Observational Survey (GUAPOS) project targets the hot molecular core (HMC) G31.41+0.31 (G31), to unveil the complex chemistry of one of the m…
H2CN/H2NC abundance ratio: a new potential temperature tracer for the interstellar medium
David San Andrés, Laura Colzi, Víctor M. Rivilla +7
The radical is the high-energy metastable isomer of radical, which has been recently detected for the first time in the interstellar medium towards a ha…
Amides inventory towards the G+0.693-0.027 molecular cloud
S. Zeng, V. M. Rivilla, I. Jiménez-Serra +6
Interstellar amides have attracted significant attentions as they are potential precursors for a wide variety of organics essential to life. However, our current understanding of t…
Kinematics of Galactic Centre clouds shaped by shear-seeded solenoidal turbulence
Maya A. Petkova, J. M. Diederik Kruijssen, Jonathan D. Henshaw +17
The Central Molecular Zone (CMZ; the central ~ 500 pc of the Galaxy) is a kinematically unusual environment relative to the Galactic disc, with high velocity dispersions and a stee…
Reconstructing the shock history in the CMZ of NGC 253 with ALCHEMI
K. -Y. Huang, S. Viti, J. Holdship +19
HNCO and SiO are well known shock tracers and have been observed in nearby galaxies, including the nearby (D=3.5 Mpc) starburst galaxy NGC 253. The simultaneous detection of these…
A sequential acid-base (SAB) mechanism in the interstellar medium: The emergence of cis formic acid in dark molecular clouds
Juan García de la Concepción, Izaskun Jiménez-Serra, José Carlos Corchado +5
The abundance ratios between isomers of a COM observed in the ISM provides valuable information about the chemistry and physics of the gas and eventually, the history of molecular…
