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…
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…
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…
