Discovery of C5H+ and detection of C3H+ in TMC-1 with the QUIJOTE line survey [PDF]
A&A 657, L16 (2022), 2022 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 that can be fit with B=2411.94397 +/-0.00055 MHz and D=138+/-3 Hz. The standard deviation of the fit is 4.4 kHz.

Discovery of two metallic cyanoacetylides in IRC+10216: HMgCCCN and NaCCCN [PDF]
A&A 672, L12 (2023), 2023 We report on the detection of a series of six lines in the ultra-deep Q-band integration toward IRC+10216 carried out with the Yebes 40m telescope, which are in harmonic relation with integer quantum numbers J from 12 to 18. After a detailed analysis of all possible carriers, guided by high-level quantum chemical calculations, we conclude that the ...

Discovery of the elusive thioketenylium, HCCS+, in TMC-1 [PDF]
A&A 657, L4 (2022), 2021 We report the detection in TMC-1 of the cation HCCS+ (3Sigma-), which is the protonated form of the widespread radical CCS. This is the first time that a protonated radical has been detected in a cold dark cloud. Twenty-six hyperfine components from twelve rotational transitions have been observed with the Yebes 40m and IRAM 30m radio telescopes.

Laboratory and astronomical discovery of the cyanovinyl radical H2CCCN [PDF]
A&A 676, L5 (2023), 2023 We report the first laboratory and interstellar detection of the alpha-cyano vinyl radical (H2CCCN). This species was produced in the laboratory by an electric discharge of a gas mixture of vinyl cyanide, CH2CHCN, and Ne, and its rotational spectrum was characterized using a Balle-Flygare narrowband-type Fourier-transform microwave spectrometer ...

The sulphur saga in TMC-1: Discovery of HCSCN and HCSCCH [PDF]
A&A 650, L14 (2021), 2021 We report the detection, for the first time in space, of cyano thioformaldehyde (HCSCN) and propynethial (HCSCCH) towards the starless core TMC-1. Cyano thioformaldehyde presents a series of prominent a- and b-type lines, which are the strongest previously unassigned features in our Q-band line survey of TMC-1.
