On the nature of the compact sources in IRAS 16293-2422 seen in at centimeter to sub-millimeter wavelengths
Antonio Hernández-Gómez, Laurent Loinard, Claire J. Chandler +10
We present multi-epoch continuum observations of the Class 0 protostellar system IRAS 16293-2422 taken with the Very Large Array (VLA) at multiple wavelengths between 7 mm and 15 c…
First detection of the pre-biotic molecule glycolonitrile (HOCH2CN) in the interstellar medium
S. Zeng, D. Quénard, I. Jiménez-Serra +4
Theories of a pre-RNA world suggest that glycolonitrile (HOCHCN) is a key species in the process of ribonucleotide assembly, which is considered as a molecular precursor of nuc…
The fate of formamide in a fragmenting protoplanetary disc
David Quénard, John D. Ilee, Izaskun Jiménez-Serra +3
Recent high-sensitivity observations carried out with ALMA have revealed the presence of complex organic molecules (COMs) such as methyl cyanide (CHCN) and methanol (CH$_…
Sulphur chemistry in the L1544 pre-stellar core
Charlotte Vastel, David Quénard, Romane Le Gal +7
The L1544 pre-stellar core has been observed as part of the ASAI IRAM 30m Large Program as well as follow-up programs. These observations have revealed the chemical richness of the…
Chemical modelling of glycolaldehyde and ethylene glycol in star-forming regions
A. Coutens, S. Viti, J. M. C. Rawlings +5
Glycolaldehyde (HOCHCHO) and ethylene glycol ((CHOH)) are two complex organic molecules detected in the hot cores and hot corinos of several star-forming regions. The e…
Phosphorus-bearing molecules in the Galactic Center
V. M. Rivilla, I. Jiménez-Serra, S. Zeng +10
Phosphorus (P) is one of the essential elements for life due to its central role in biochemical processes. Recent searches have shown that P-bearing molecules (in particular PN and…
High spectral resolution observations of HNC3 and HCCNC in the L1544 prestellar core
C. Vastel, K. Kawaguchi, D. Quénard +4
HCCNC and HNC3 are less commonly found isomers of cyanoacetylene, HC3N, a molecule that is widely found in diverse astronomical sources. We want to know if HNC3 is present in sourc…
Chemical modelling of complex organic molecules with peptide-like bonds in star-forming regions
David Quénard, Izaskun Jiménez-Serra, Serena Viti +2
Peptide bonds (N-C=O) play a key role in metabolic processes since they link amino acids into peptide chains or proteins. Recently, several molecules containing peptide-like bonds…
The ALMA Frontier Fields Survey - II. Multiwavelength Photometric analysis of 1.1mm continuum sources in Abell 2744, MACSJ0416.1-2403 and MACSJ1149.5+2223
N. Laporte, F. E. Bauer, P. Troncoso-Iribarren +32
[abridged] The Hubble and Spitzer Space Telescope surveys of the Frontier Fields (FF) provide extremely deep images around six massive, strong-lensing clusters of galaxies. The ALM…
Detection of the HCNH and HCNH ions in the L1544 pre-stellar core
David Quénard, Charlotte Vastel, Cecilia Ceccarelli +3
The L1544 pre-stellar core was observed as part of the ASAI (Astrochemical Surveys At IRAM) Large Program. We report the first detection in a pre-stellar core of the HCNH and H…
Modelling the 3D physical structure of astrophysical sources with GASS
D. Quénard, S. Bottinelli, E. Caux
The era of interferometric observations leads to the need of a more and more precise description of physical structures and dynamics of star-forming regions, from pre-stellar cores…
Detectability of deuterated water in prestellar cores
David Quénard, Vianney Taquet, Charlotte Vastel +2
Water is an important molecule in the chemical and thermal balance of dense molecular gas, but knowing its history through-out the various stages of the star formation is a fundame…
