Using the QUIJOTE line survey in the 32.0–50.4GHz range, we report the discovery of the molecule CH 2 CCHC 4 H towards the prestellar cold core TMC-1 in the Taurus region. We also present a rigorous detection of CH 2 CCHC 3 N, along with its detailed analysis. We identified a total of twenty rotational transitions for each one of these molecules. The rotational quantum numbers range from J u = 17 up to 24 and K a ≤ 3. The column density for CH 2 CCHC 4 H is N = (2 . 2 ± 0 . 2) × 10 12 cm − 2…

The QUIJOTE line survey of TMC-1

We present the recent results obtained with the QUIJOTE line survey of the cold dark core TMC-1. The observations have been carried out with the YEBES 40m radio telescope (see Figure 1) in the Q-band
