The Herschel M33 extended survey (HerM33es): PACS spectroscopy of the star forming region BCLMP 302
B. Mookerjea, C. Kramer, C. Buchbender +19
Context: The emission line of [CII] at 158 micron is one of the strongest cooling lines of the interstellar medium (ISM) in galaxies. Aims: Disentangling the relative contributions…
Detection of OH and HO towards Orion~KL
H. Gupta, P. Rimmer, J. C. Pearson +76
We report observations of the reactive molecular ions OH, HO, and HO towards Orion KL with Herschel/HIFI. All three fine-structure transitions of OH…
Gas morphology and energetics at the surface of PDRs: new insights with Herschel observations of NGC 7023
C. Joblin, P. Pilleri, J. Montillaud +37
We investigate the physics and chemistry of the gas and dust in dense photon-dominated regions (PDRs), along with their dependence on the illuminating UV field. Using Herschel-HIFI…
The distribution of water in the high-mass star-forming region NGC 6334I
M. Emprechtinger, D. C. Lis, T. Bell +66
We present observations of twelve rotational transitions of H2O-16, H2O-18, and H2O-17 toward the massive star-forming region NGC 6334 I, carried out with Herschel/HIFI as part of…
HIFI spectroscopy of low-level water transitions in M82
A. Weiss, M. A. Requena-Torres, R. Guesten +23
We present observations of the rotational ortho-water ground transition, the two lowest para-water transitions, and the ground transition of ionised ortho-water in the archetypal s…
Herschel observations of ortho- and para-oxidaniumyl (H2O+) in spiral arm clouds toward Sgr B2(M)
P. Schilke, C. Comito, H. S. P. Mueller +55
H2O+ has been observed in its ortho- and para- states toward the massive star forming core Sgr B2(M), located close to the Galactic center. The observations show absorption in all…
