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…
Expansion Signatures in 35 HII Regions traced by SOFIA [CII] Emission
Timothy Faerber, Loren D. Anderson, Matteo Luisi +6
We analyze the expansion signatures of 35 HII regions mapped in [CII] 158 micron emission by the Stratospheric Observatory for Infrared Astronomy (SOFIA). The [CII] emission primar…
[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)…
Extended atomic carbon around molecular clouds
V. Ossenkopf-Okada, A. Karska, M. Benedettini +2
Models predict that atomic carbon occurs at the surface and in the process of the formation of molecular clouds, making its fine structure transitions a diagnostic of cloud formati…
