Discovery of interstellar NC4NH+: dicyanopolyynes are indeed abundant in space
M. Agundez, C. Cabezas, N. Marcelino +4
The previous detection of two species related to the non polar molecule cyanogen (NCCN), its protonated form (NCCNH+) and one metastable isomer (CNCN), in cold dense clouds support…
Laboratory rotational spectroscopy and astronomical search of ethynyl substituted naphthalene
Carlos Cabezas, Isabel Peña, José Cernicharo
The recent interstellar detection of cyanonaphthalenes bring interest in related aromatic molecular species that could be present in similar astronomical environments. In this cont…
Laboratory and astronomical discovery of magnesium dicarbide, MgC
P. B. Changala, H. Gupta, J. Cernicharo +6
We report the detection of magnesium dicarbide, MgC, in the laboratory at centimeter wavelengths and assign MgC, MgC, and MgC to 14 unidentifie…
Discovery of two new interstellar molecules with QUIJOTE: HCCCHCCC and HCCCCS
R. Fuentetaja, M. Agúndez, C. Cabezas +5
We report on the discovery of two new molecules, HCCCHCCC and HCCCCS, towards the starless core TMC-1 in the Taurus region from the QUIJOTE line survey in the 31.1-50.2 GHz frequen…
Discovery of fulvenallene in TMC-1 with the QUIJOTE line survey
José Cernicharo, Raúl Fuentetaja, Marcelino Agúndez +6
We report the detection of fulvenallene (-CHCCH) in the direction of TMC-1 with the QUIJOTE line survey. Thirty rotational transitions with =0,1,2,3 and =9-1…
Discovery of five cyano derivatives of propene with the QUIJOTE line survey
José Cernicharo, Raúl Fuentetaja, Carlos Cabezas +5
We report the discovery of five cyano derivatives of propene towards TMC-1 with the QUIJOTE line survey: and -crotononitrile (-CHCHCHCN, -CHCHCHCN), meth…
Discovery of CH2CCHC4H and a rigorous detection of CH2CCHC3N in TMC-1 with the QUIJOTE line survey
R. Fuentetaja, C. Cabezas, M. Agundez +5
Using the QUIJOTE line survey in the 32.0-50.4 GHz range, we report the discovery of the molecule CH2CCHC4H towards the prestellar cold core TMC-1 in the Taurus region. We also pre…
Discovery of the cyclic C5H radical in TMC-1
Carlos Cabezas, Marcelino Agundez, Raul Fuentetaja +6
Cyclic C5H (c-C5H), the radical formed by substituting an ethynyl group CCH for the hydrogen atom in the c-C3H radical, has been detected for the first time in the space. The c-C5H…
A new protonated molecule discovered in TMC-1: HCCNCH+
M. Agundez, C. Cabezas, N. Marcelino +4
In recent years we have seen an important increase in the number of protonated molecules detected in cold dense clouds. Here we report the detection in TMC-1 of HCCNCH+, the proton…
Discovery of a new molecular ion, HC7NH+, in TMC-1
C. Cabezas, M. Agundez, N. Marcelino +4
We report the detection of the protonated form of HC7N in TMC-1. The discovery of the cation HC7NH+ was carried out via the observation of nine harmonically related lines in the Q-…
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…
