The trans/cis ratio of formic, HCOOH, and thioformic, HC(O)SH, acids in the Interstellar Medium
J. García de la Concepción, L. Colzi, I. Jiménez-Serra +6
We studied theoretically the cis-trans isomerization reactions of two astrophysically relevant acids, formic acid (HCOOH) and thioformic acid (HC(O)SH), where the latter has recent…
Probing the chemical complexity of amines in the ISM: detection of vinylamine (CHNH) and tentative detection of ethylamine (CHNH)
Shaoshan Zeng, Izaskun Jiménez-Serra, Víctor M. Rivilla +8
Amines, in particular primary amines (R-NH) are closely related to the primordial synthesis of amino acids since they share the same structural backbone. However, only limited…
ALCHEMI: an ALMA Comprehensive High-resolution Extragalactic Molecular Inventory. Survey presentation and first results from the ACA array
S. Martín, J. G. Mangum, N. Harada +32
We used the Atacama Large Millimeter/submillimeter Array (ALMA), covering a nearly contiguous 289 GHz frequency range between 84.2 and 373.2 GHz, to image the continuum and spectra…
First detection of CHNCO in the ISM and search of other isocyanates towards the G+0.693-0.027 molecular cloud
L. F. Rodríguez Almeida, V. M. Rivilla, I. Jiménez-Serra +9
Little is known about the chemistry of isocyanates (compounds with the functional group R-N=C=O) in the interstellar medium, as only four of them have been detected so far: isocyan…
Starburst Energy Feedback Seen Through HCO/HOC Emission in NGC 253 from ALCHEMI
Nanase Harada, Sergio Martín, Jeffrey G. Mangum +19
Molecular abundances are sensitive to UV-photon flux and cosmic-ray ionization rate. In starburst environments, the effects of high-energy photons and particles are expected to be…
The GUAPOS project II. A comprehensive study of peptide-like bond molecules
L. Colzi, V. M. Rivilla, M. T. Beltrán +12
Peptide-like bond molecules, which can take part to the formation of proteins in a primitive Earth environment, have been detected up to now only towards a few sources. We present…
Detection of the cyanomidyl radical (HNCN): a new interstellar species with the NCN backbone
V. M. Rivilla, I. Jiménez-Serra, J. García de la Concepción +9
We report here the first detection in the interstellar medium of the cyanomidyl radical (HNCN). Using the Yebes 40m and the IRAM 30m telescopes, we have targeted the doublets of th…
The TOPGöt high-mass star-forming sample. I. Methyl cyanide emission as tracer of early phases of star formation
C. Mininni, F. Fontani, A. Sánchez-Monge +9
The TOPGöt project studies a sample of 86 high-mass star-forming regions in different evolutionary stages from starless cores to ultra compact HII regions. The aim of the survey is…
The Distribution and Origin of CH in NGC 253 from ALCHEMI
J. Holdship, S. Viti, S. Martín +18
Observations of chemical species can provide an insight into the physical conditions of the emitting gas but it is important to understand how their abundances and excitation vary…
Discovery in space of ethanolamine, the simplest phospholipid head group
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesús Martín-Pintado +9
Cell membranes are a key element of life because they keep the genetic material and metabolic machinery together. All present cell membranes are made of phospholipids, yet the natu…
First survey of HCNH in high-mass star-forming cloud cores
F. Fontani, L. Colzi, E. Redaelli +2
Most stars in the Galaxy, including the Sun, were born in high-mass star-forming regions. It is hence important to study the chemical processes in these regions to better understan…
Thiols in the ISM: first detection of HC(O)SH and confirmation of CHSH
Lucas F. Rodríguez-Almeida, Izaskun Jiménez-Serra, Víctor M. Rivilla +8
The chemical compounds carrying the thiol group (-SH) have been considered essential in recent prebiotic studies regarding the polymerization of amino acids. We have searched for t…
