CII fine-structure line observations of the Sagittarius C Region in the Galaxy's Central Molecular Zone

DEnise Riquelme-Vasquez, Rolf Guesten, Mark R. Morris +7

Context. Sagittarius C (Sgr C) is a massive, relatively quiescent complex at the western edge of the Galaxy's Central Molecular Zone (CMZ). While the Sgr B2 region has been extensi…

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…

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…

Molecular cloud matching in CO and dust in M33 II. Physical properties of giant molecular clouds

Eduard Keilmann, Slawa Kabanovic, Nicola Schneider +8

Understanding mass, size, and surface mass density of giant molecular clouds (GMCs) in galaxies is key to insights into star formation processes. We analyze these in M33 using Hers…
