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…
Discovery of two isomers of ethynyl cyclopentadiene in TMC-1: Abundances of CCH and CN derivatives of hydrocarbon cycles
J. Cernicharo, M. Agundez, R. I. Kaiser +5
We report the detection of two isomers of ethynyl cyclopentadiene (c-C5H5CCH), namely 1- and 2-ethynyl-1,3-cyclopentadiene, in the direction of TMC-1. We derive column densities of…
Discovery of interstellar 3-cyano propargyl radical, CH2CCCN
Carlos Cabezas, Marcelino Agundez, Nuria Marcelino +4
We report the first detection in interstellar space of the 3-cyano propargyl radical (CH2C3N). This species was observed in the cold dark cloud TMC-1 using the Yebes 40m telescope.…
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…
Interstellar detection of the simplest aminocarbyne, H2NC: an ignored but abundant molecule
C. Cabezas, M. Agundez, N. Marcelino +3
We report the first identification in space of H2NC, a high-energy isomer of H2CN that has been largely ignored in chemical and astrochemical studies. The observation of various un…
