Discovery of interstellar phenalene (-CH): A new piece for the chemical puzzle of PAHs in space
Carlos Cabezas, Marcelino Agúndez, Cristóbal Pérez +10
We present the discovery of the unsubstituted polycyclic aromatic hydrocarbon (PAH) phenalene (-CH) in TMC-1 as part of the QUIJOTE line survey. In spite of the lo…
A search for the three isomers of cyano-1,3-butadiene in TMC-1: Implications for bottom-up routes involving 1,3-butadiene
M. Agundez, C. Cabezas, N. Marcelino +4
The molecule 1,3-butadiene (CH2CHCHCH2) could play a key role in the synthesis of the cyclic molecules cyclopentadiene and benzene in cold dense clouds. Since 1,3-butadiene is non-…
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…
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-…
Ionise hard: interstellar PO detection
Víctor M. Rivilla, Juan García de la Concepción, Izaskun Jiménez-Serra +13
We report the first detection of the phosphorus monoxide ion (PO) in the interstellar medium. Our unbiased and very sensitive spectral survey towards the G+0.6930.027 mole…
Pure hydrocarbon cycles in TMC-1: Discovery of ethynyl cyclopropenylidene, cyclopentadiene and indene
J. Cernicharo, M. Agundez, C. Cabezas +4
We report the detection for the first time in space of three new pure hydrocarbon cycles in TMC-1: c-C3HCCH (ethynyl cyclopropenylidene), c-C5H6 (cyclopentadiene) and c-C9H8 (inden…
Discovery of the acetyl cation, CH3CO+, in space and in the laboratory
J. Cernicharo, C. Cabezas, S. Bailleux +10
Using the Yebes 40m and IRAM 30m radiotelescopes, we detected two series of harmonically related lines in space that can be fitted to a symmetric rotor. The lines have been seen to…
New molecular species at redshift z=0.89
B. Tercero, J. Cernicharo, S. Cuadrado +2
We present the first detections of CH3SH, C3H+, C3N, HCOOH, CH2CHCN, and H2CN in an extragalactic source. Namely the spiral arm of a galaxy located at z=0.89 on the line of sight t…
