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…
SOFIA FEEDBACK Survey: The Eagle Nebula in [C II] and Molecular Lines
Ramsey L. Karim, Marc W. Pound, Alexander G. G. M. Tielens +15
We characterize the physical conditions and energy budget of the M16 H II region using SOFIA FEEDBACK observations of the [C II] 158 m line. The O stars in the $\sim 10^{4}~{\r…
Measuring Interstellar Carbon Abundance via 158 um [CII] Absorption with SOFIA -- A Potential Detection, and Proof-of-Concept for Depletion Studies with Future Far-IR Facilities
Christopher J. R. Clark, Julia. C. Roman-Duval, Suzanne C. Madden Marc Mertens +4
Carbon plays key roles in the InterStellar Medium (ISM) -- as a constituent of dust, as the carrier of the dominant far-infrared cooling line, and as a component of various importa…
SOFIA/upGREAT imaging spectroscopy of the [C II] 158 um fine structure line toward the Sgr A region in the Galactic center
A. I. Harris, R. Güsten, M. A. Requena-Torres +8
We present SOFIA/upGREAT velocity-resolved spectral imaging and analysis of the 158 um [C II] spectral line toward the central 80 by 43\,pc region of the Central Molecular Zone of…
