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 towards the cold dense cores TMC-1, L483, L1527, and L1544. High level o

Discovery of the ubiquitous cation NS+ in space confirmed by laboratory spectroscopy

Autor: Cernicharo, J., Lefloch, B., Agundez, M., Bailleux, S., Margules, L., Roueff, E., Bachiller, R., Marcelino, N., Tercero, B., Vastel, C., Caux, E.

We report the detection in space of a new molecular species which has been characterized spectroscopically and fully identified from astrophysical data. The observations were carried out with the 30m IRAM telescope. The molecule is ubiquitous as its

Tentative Detection of the Nitrosylium Ion in Space

Autor: Cernicharo, J., Bailleux, S., Alekseev, E., Fuente, A., Roueff, E., Gerin, M., Tercero, B., Treviño-Morales, S. P., Marcelino, N., Bachiller, R., Lefloch, B.

We report the tentative detection in space of the nitrosylium ion, NO$^+$. The observations were performed towards the cold dense core Barnard 1-b. The identification of the NO$^+$ $J$=2--1 line is supported by new laboratory measurements of NO$^+$ r
