Ionized gas in the Scutum spiral arm as traced in [N II] and [C II]
W. D. Langer, T. Velusamy, P. F. Goldsmith +5
Determining the properties of the warm ionized medium (WIM) at the leading edge of spiral arms is important for understanding its dynamics and cloud formation. The inner edge of th…
Characterizing the transition from diffuse atomic to dense molecular clouds in the Magellanic clouds with [CII], [CI], and CO
Jorge L. Pineda, William D. Langer, Paul F. Goldsmith +8
We present and analyze deep Herschel/HIFI observations of the [CII] 158um, [CI] 609um, and [CI] 370um lines towards 54 lines-of-sight (LOS) in the Large and Small Magellanic clouds…
Thermal Pressure in Diffuse H2 Gas Measured by Herschel [C II] Emission and FUSE UV H2 Absorption
Thangasamy Velusamy, William Langer, Paul Goldsmith +1
UV absorption studies with FUSE have observed H2 molecular gas in translucent and diffuse clouds. Observations of the 158 micron [C II] fine structure line with Herschel also trace…
Kinematics and properties of the Central Molecular Zone as probed with [C II]
W. D. Langer, T. Velusamy, M. R. Morris +2
The Galactic Central Molecular Zone (CMZ) is a region containing massive and dense molecular clouds, with dynamics driven by a variety of energy sources including a massive black h…
Internal structure of spiral arms traced with [CII]: Unraveling the WIM, HI, and molecular emission lanes
T. Velusamy, W. D. Langer, P. F. Goldsmith +1
The spiral arm tangencies are ideal lines of sight in which to determine the distribution of interstellar gas components in the spiral arms and study the influence of spiral densit…
Ionized gas at the edge of the Central Molecular Zone
W. D. Langer, P. F. Goldsmith, J. L. Pineda +3
To determine the properties of the ionized gas at the edge of the CMZ near Sgr E we observed a small portion of the edge of the CMZ near Sgr E with spectrally resolved [C II] 158 m…
