First detection of C2H+ in the interstellar medium
Arshia M. Jacob, Karl M. Menten, Sandra Brünken +10
Despite the detection of nearly 350 molecules in the interstellar medium, almost half of which are carbon chains, the pathways that build molecular complexity remain poorly underst…

Investigation of the rotational spectrum of CHOH and its tentative detection toward Sagittarius B2(N)
Holger S. P. Müller, Vadim V. Ilyushin, Arnaud Belloche +2
Methanol is an abundant molecule in space. The column density of CHOH is in some star-forming regions so high that the search for CHOH is promising. But only very…

A low cosmic-ray ionisation rate in the prestellar core Ophiuchus/H-MM1. Mapping of the molecular ions ortho-H2D+, N2H+, and DCO+
Jorma Harju, Charlotte Vastel, Olli Sipilae +5
(abridged) We have mapped the prestellar core H-MM1 in Ophiuchus in rotational lines of ortho-H2D+ (oH2D+), N2H+, and DCO+ at the wavelength 0.8 mm with the Large APEX sub-Millimet…
