Collisional Excitation of the [CII] Fine Structure Transition in Interstellar Clouds
Paul F. Goldsmith, William D. Langer, Jorge L. Pineda +1
We analyze the collisional excitation of the 158 micron (1900.5 GHz) fine structure transition of ionized carbon (C+) in terms of line intensities produced by simple cloud models.…
Submillimeter Line Emission from LMC 30Dor: The Impact of a Starburst on a Low Metallicity Environment
Jorge L. Pineda, Norikazu Mizuno, Markus Roellig +4
(Abridged) The 30 Dor region in the Large Magellanic Cloud (LMC) is the most vigorous star-forming region in the Local Group. Star formation in this region is taking place in low-m…
[CII] 158 micron line detection of the warm ionized medium in the Scutum--Crux spiral arm tangency
T. Velusamy, W. D. Langer, J. L. Pineda +1
HIFI GOT C+ Galactic plane [CII] spectral survey has detected strong emission at the spiral arm tangencies. We use the unique viewing geometry of the Scutum-Crux (S-C) tangency nea…
The Life and Death of Dense Molecular Clumps in the Large Magellanic Cloud
Jonathan P. Seale, Leslie W. Looney, Tony Wong +3
We report the results of a high spatial (parsec) resolution HCO+ (J = 1-0) and HCN (J = 1-0) emission survey toward the giant molecular clouds of the star formation regions N105, N…
