Analysis of the isotopologues of CS, CCS, CCCS, HCS+, HCCS+, and H2CS in TMC-1 with the QUIJOTE line survey
R. Fuentetaja, C. Cabezas, Y. Endo +7
We performed a detailed analysis of the isotopologues with 13C, 34S, 33S, and 36S of the sulphur-bearing molecules CS, CCS, CCCS,HCS+, HCCS+, and H2CS towards TMC-1 using the QUIJO…
Identification of the interstellar 1-cyano propargyl radical (HCCCHCN) in TMC-1
C. Cabezas, M. Agúndez, N. Marcelino +7
We report the first detection in interstellar medium of the 1-cyano propargyl radical, HCHCN. This species is an isomer of the 3-cyano propargyl radical (CHCN), which w…
Discovery of two cyano derivatives of acenaphthylene (CH) in TMC-1 with the QUIJOTE line survey
J. Cernicharo, C. Cabezas, R. Fuentetaja +12
We report the discovery in TMC-1 of two cyano derivatives of the PAH acenaphthylene (CH). We have found two series of lines with the QUIJOTE line survey that we assign t…
The rich interstellar reservoir of dinitriles: Detection of malononitrile and maleonitrile in TMC-1
M. Agundez, C. Bermudez, C. Cabezas +7
While the nitrile group is by far the most prevalent one among interstellar molecules, the existence of interstellar dinitriles (molecules containing two -CN groups) has recently b…
Discovery of the interstellar cyanoacetylene radical cation HCN
C. Cabezas, M. Agúndez, Y. Endo +4
We report the first identification in space of HCN, the simplest member of the family of cyanopolyyne cations. Three rotational transitions with half-integer quantum number…
QUIJOTE discovery of the cation radicals HC5N+ and HC7N+
J. Cernicharo, C. Cabezas, M. Agúndez +4
We present the discovery with the QUIJOTE line survey of the cations HC5N+ and HC7N+ in the direction of TMC-1. Seven lines with half-integer quantum numbers from J=25/2-23/2 to 37…
Laboratory and astronomical discovery of cyanothioketene, NCCHCS, in the cold starless core TMC-1
C. Cabezas, M. Agúndez, Y. Endo +5
We present the detection of cyanothioketene, NCCHCS, in the laboratory and toward TMC-1. This transient species was produced through a discharge of a gas mixture of CH2CHCN and CS2…
Space and laboratory observation of the deuterated cyanomethyl radical HDCCN
Carlos Cabezas, Yasuki Endo, Evelyne Roueff +4
Our observations of TMC-1 with the Yebes 40 m radio telescope in the 31.0-50.3 GHz range allowed us to detect a group of unidentified lines, showing a complex line pattern indicati…
Discovery of HC3O+ in space: The chemistry of O-bearing species in TMC-1
J. Cernicharo, N. Marcelino, M. Agundez +5
Using the Yebes 40m and IRAM 30m radio telescopes, we detected a series of harmonically related lines with a rotational constant B0=4460.590 +/- 0.001 MHz and a distortion constant…
