Detection of extragalactic CF+ toward PKS1830-211 -- Chemical differentiation in the absorbing gas

S. Muller, K. Kawaguchi, J. H. Black +1

We report the first extragalactic detection of CF+, the fluoromethylidynium ion, in the z=0.89 absorber toward PKS1830-211. We estimate an abundance of ~3E-10 relative to H2 and th…

Observations of Ammonia in External Galaxies. II. Maffei 2

Shuro Takano, Naomasa Nakai, Kentarou Kawaguchi +1

The ammonia (J,K) = (1,1), (2,2), (3,3), and (4,4) transitions at 23.7 -- 24.1 GHz region were searched for in a nearby galaxy Maffei 2 to study relation between molecular abundanc…

Identification of SH $Δ v = 1$ ro-vibrational lines in R And

I. Yamamura, K. Kawaguchi, S. T. Ridgway

We report the identification of SH $Δ v = 1$ ro-vibrational lines in the published high-resolution infrared spectrum of the S-type star, R And. This is the first astronomical detectio…
