Space as a spectroscopic laboratory: High-resolution spectroscopy of the [C II] hyperfine structure with SOFIA/upGREAT
S. Kabanovic, V. Ossenkopf-Okada, S. Schlemmer +13
The paper uses high‑resolution SOFIA/upGREAT observations of the 158 µm [13C II] line to directly measure its hyperfine splitting and determine the magnetic‑dipole hyperfine consta…
Hyperfine-Resolved Rovibrational and Rotational Spectroscopy of OH ()
Weslley G. D. P. Silva, Lea Schneider, Urs U. Graf +6
The OH () radical cation has been investigated by combining a 4 K 22-pole ion trap apparatus with high-resolution IR and THz radiation sources. Applying different typ…
The Diamond Ring in Cygnus X: Advanced stage of an expanding bubble of ionised carbon
Simon M. Dannhauer, Sebastian Vider, Nicola Schneider +18
The "Diamond Ring" in Cygnus X, southwest of the DR21 ridge, is a nearly circular structure of 6 pc in diameter, prominent in FIR emission and enclosed by clumpy molecular cl…
[C II]-deficit caused by self-absorption in an ionized carbon-filled bubble in RCW79
Eduard Keilmann, Simon Dannhauer, Slawa Kabanovic +12
Recent spectroscopic observations of the [C II] 158 fine-structure line of ionized carbon (C), using the Stratospheric Observatory for Infrared Astronomy (SOFIA…
