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…
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…
Molecular precursors of the RNA-world in space: new nitriles in the G+0.693-0.027 molecular cloud
Víctor M. Rivilla, Izaskun Jiménez-Serra, Jesus Martín-Pintado +10
Nitriles play a key role as molecular precursors in prebiotic experiments based on the RNA-world scenario for the origin of life. These chemical compounds could have been partially…
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…
