Laboratory and astronomical discovery of the cyanovinyl radical H2CCCN
C. Cabezas, J. Tang, M. Agúndez +9
We report the first laboratory and interstellar detection of the alpha-cyano vinyl radical (H2CCCN). This species was produced in the laboratory by an electric discharge of a gas m…
The magnesium paradigm in IRC+10216: Discovery of MgCH, MgCN, MgCH, and MgCN
J. Cernicharo, C. Cabezas, J. R. Pardo +7
We found four series of harmonically related lines in IRC\,+10216 with the Yebes\,40m and IRAM\,30m telescopes. The first series corresponds to a molecule with a rotational constan…
Discovery of two metallic cyanoacetylides in IRC+10216: HMgCCCN and NaCCCN
C. Cabezas, J. R. Pardo, M. Agundez +6
We report on the detection of a series of six lines in the ultra-deep Q-band integration toward IRC+10216 carried out with the Yebes 40m telescope, which are in harmonic relation w…
Discovery of C5H+ and detection of C3H+ in TMC-1 with the QUIJOTE line survey
J. Cernicharo, M. Agundez, C. Cabezas +6
We report the discovery of the C5H+ cation toward TMC-1 with the QUIJOTE line survey. Four lines from J=7-6 up to J=10-9 have been identified in perfect harmonic frequency relation…
Discovery of the elusive thioketenylium, HCCS+, in TMC-1
C. Cabezas, M. Agundez, N. Marcelino +6
We report the detection in TMC-1 of the cation HCCS+ (3Sigma-), which is the protonated form of the widespread radical CCS. This is the first time that a protonated radical has bee…
Laboratory observation and astronomical search of 1-cyano propargyl radical, HCCCHCN
C. Cabezas, M. Nakajima, C. H. Chang +3
The reaction between carbon atoms and vinyl cyanide, CH2CHCN, is a formation route to interstellar 3-cyano propargyl radical, CH2C3N, a species that has recently been discovered in…
Evolution of Morphological and Physical Properties of Laboratory Interstellar Organic Residues with Ultraviolet Irradiation
Laurette Piani, Shogo Tachibana, Tetsuya Hama +15
Refractory organic compounds formed in molecular clouds are among the building blocks of the solar system objects and could be the precursors of organic matter found in primitive m…
