On the abiotic origin of dimethyl sulfide: discovery of DMS in the Interstellar Medium
Miguel Sanz-Novo, Víctor M. Rivilla, Christian P. Endres +14
Following the discovery of dimethyl sulfide (CHSCH, DMS) signatures in comet 67P/Churyumov-Gerasimenko, we report the first detection of this organosulfur species in the in…
Discovery of MgS and NaS in the Interstellar Medium and tentative detection of CaO
M. Rey-Montejo, I. Jimenez-Serra, J. Martin-Pintado +12
We report the first detection of the metal-bearing molecules sodium sulfide (NaS) and magnesium sulfide (MgS) and the tentative detection of calcium monoxide (CaO) in the interstel…
The science case and challenges of space-borne sub-millimeter interferometry
Leonid I. Gurvits, Zsolt Paragi, Ricardo I. Amils +51
Ultra-high angular resolution in astronomy has always been an important vehicle for making fundamental discoveries. Recent results in direct imaging of the vicinity of the supermas…
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…
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…
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…
Discovery of benzyne, o-C6H4, in TMC-1 with the QUIJOTE line survey
J. Cernicharo, M. Agundez, R. I. Kaiser +5
We report the detection, for the first time in space, of a new non-functionalised hydrocarbon cycle in the direction of TMC-1: o-C6H4 (ortho-benzyne). We derive a column density fo…
Magnesium radicals MgCN and MgCH in IRC+10216
J. R. Pardo, C. Cabezas, J. P. Fonfría +5
After the previous discovery of MgCN and MgCH in IRC+10216, a deeper Q-band (31.0-50.3 GHz) integration on this source had revealed two additional series of harmonically re…
Detection of deuterated methylcyanoacetylene, CHDCN, in TMC-1
C. Cabezas, E. Roueff, B. Tercero +4
We report the first detection in space of the single deuterated isotopologue of methylcyanoacetylene, CHDCN. A total of fifteen rotational transitions, with = 8-12 and…
The sulphur saga in TMC-1: Discovery of HCSCN and HCSCCH
J. Cernicharo, C. Cabezas, Y. Endo +5
We report the detection, for the first time in space, of cyano thioformaldehyde (HCSCN) and propynethial (HCSCCH) towards the starless core TMC-1. Cyano thioformaldehyde presents a…
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…
O-bearing complex organic molecules at the cyanopolyyne peak of TMC-1: detection of C2H3CHO, C2H3OH, HCOOCH3, and CH3OCH3
M. Agundez, N. Marcelino, B. Tercero +3
We report the detection of the oxygen-bearing complex organic molecules propenal (C2H3CHO), vinyl alcohol (C2H3OH), methyl formate (HCOOCH3), and dimethyl ether (CH3OCH3) toward th…
TMC-1, the starless core sulfur factory: Discovery of NCS, HCCS, H2CCS, H2CCCS, and C4S and detection of C5S
J. Cernicharo, C. Cabezas, M. Agundez +7
We report the detection of the sulfur-bearing species NCS, HCCS, H2CCS, H2CCCS, and C4S for the first time in space. These molecules were found towards TMC-1 through the observatio…
Discovery of the propargyl radical (CH2CCH) in TMC-1: one of the most abundant radicals ever found and a key species for cyclization to benzene in cold dark clouds
M. Agundez, C. Cabezas, B. Tercero +4
We present the first identification in interstellar space of the propargyl radical (CH2CCH). This species was observed in the cold dark cloud TMC-1 using the Yebes 40m telescope. T…
