===== Fluoromethylidynium, CF+, in Extragalactic Sources ===== S. Muller, K. Kawaguchi, J. H. Black, and T. Amano,\\ reported on the\\ **[[https://doi.org/10.1051/0004-6361/201628494|Detection of Extragalactic CF+ toward PKS 1830–211 – Chemical Differentiation in the Absorbing Gas]]**\\ //Astron. Astrophys.// **589**, (2016) Art. No. L5.\\ The //J// = 2 – 1 transition of CF+ (rest frequency 205.2 GHz) was observed in absorption in the //z// = 0.89 foreground galaxy toward the quasar PKS 1830–211. The Atacama Large Millimeter Array (ALMA) was used in its Early Science Cycle 2 phase. ---- Contributor(s): H. S. P. Müller; 04, 2016 ----
