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…
HyGAL: Characterizing the Galactic ISM with observations of hydrides and other small molecules. III. The absorption lines of [O I], CH, and OH
W. -J. Kim, A. M. Jacob, D. A. Neufeld +17
The HyGAL Stratospheric Observatory for Infrared Astronomy (SOFIA) legacy program aims at characterizing the interstellar medium in the Milky Way using hydrides, [C II], and [O I]…
Globules and pillars in Cygnus X IV. Velocity-resolved [OI] 63 mu map of a peculiar proplyd-like object
N. Schneider, S. Dannhauer, E. Keilmann +14
We investigated an isolated, globule-shaped object (0.37x0.11 pc), located near the centre of the Cygnus OB2 cluster and named proplyd #7 in optical observations. The source can be…
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…
Tight correlation of star formation with [Ci] and CO lines across cosmic time
Theodoros Topkaras, Thomas G. Bisbas, Zhi-Yu Zhang +1
Context. Cold molecular gas tracers, such as CI and CO lines, have been widely used to infer specific characteristics of the ISM and to derive star-formation relations among galaxi…
The HI-to-H2 transition in the Draco cloud
Nicola Schneider, Volker Ossenkopf-Okada, Markus Roellig +7
In recent decades, significant attention has been dedicated to analytical and observational studies of the atomic hydrogen (HI) to molecular hydrogen (H2) transition in the interst…
