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…
The [OI] fine structure line profiles in Mon R2 and M17 SW: the puzzling nature of cold foreground material identified by [12CII] self-absorption
C. Guevara, J. Stutzki V. Ossenkopf-Okada, U. Graf +8
Context. Recent studies of the optical depth comparing [12CII] and [13CII] line profiles in Galactic star-forming regions revealed strong self-absorption in [12CII] by low excitati…
Unveiling the formation of the massive DR21 ridge
L. Bonne, S. Bontemps, N. Schneider +10
We present new CO(1-0), CO(1-0), HCO(1-0) and HCO(1-0) maps from the IRAM 30m telescope, and a spectrally-resolved [CII] 158 m map observed with…
FEEDBACK: a SOFIA Legacy Program to Study Stellar Feedback in Regions of Massive Star Formation
N. Schneider, R. Simon, C. Guevara +37
FEEDBACK is a SOFIA legacy program dedicated to study the interaction of massive stars with their environment. It performs a survey of 11 galactic high mass star forming regions in…
[CII] 158 μm self-absorption and optical depth effects
C. Guevara, J. Stutzki, V. Ossenkopf-Okada +7
Context. The [CII] 158 μm far-infrared (FIR) fine-structure line is one of the most important cooling lines of the star-forming interstellar medium (ISM). High spectral resolution…
First astrophysical detection of the helium hydride ion (HeH)
Rolf Güsten, Helmut Wiesemeyer, David Neufeld +7
During the dawn of chemistry when the temperature of the young Universe had fallen below 4000 K, the ions of the light elements produced in Big Bang nucleosynthesis recombine…
