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…
Herschel observations of EXtra-Ordinary Sources (HEXOS): Observations of H2O and its isotopologues towards Orion KL
G. J. Melnick, V. Tolls, D. A. Neufeld +49
We report the detection of more than 48 velocity-resolved ground rotational state transitions of H2(16)O, H2(18)O, and H2(17)O - most for the first time - in both emission and abso…
Reversal of infall in SgrB2(M) revealed by Herschel/HIFI observations of HCN lines at THz frequencies
Rainer Rolffs, Peter Schilke, Claudia Comito +54
To investigate the accretion and feedback processes in massive star formation, we analyze the shapes of emission lines from hot molecular cores, whose asymmetries trace infall and…
A Sample of [CII] Clouds Tracing Dense Clouds in Weak FUV Fields observed by Herschel
Jorge L. Pineda, Thangasamy Velusamy, William D. Langer +4
The [CII] fine--structure line at 158um is an excellent tracer of the warm diffuse gas in the ISM and the interfaces between molecular clouds and their surrounding atomic and ioniz…
First detection of ND in the solar-mass protostar IRAS16293-2422
A. Bacmann, E. Caux, P. Hily-Blant +64
In the past decade, much progress has been made in characterising the processes leading to the enhanced deuterium fractionation observed in the ISM and in particular in the cold, d…
Herschel/HIFI observations of spectrally resolved methylidyne signatures toward the high-mass star-forming core NGC6334I
M. H. D. van der Wiel, F. F. S. van der Tak, D. C. Lis +65
In contrast to extensively studied dense star-forming cores, little is known about diffuse gas surrounding star-forming regions. We study molecular gas in the high-mass star-formin…
Herschel observations of EXtra-Ordinary Sources: The Terahertz spectrum of Orion KL seen at high spectral resolution
N. R. Crockett, E. A. Bergin, S. Wang +60
We present the first high spectral resolution observations of Orion KL in the frequency ranges 1573.4 - 1702.8 GHz (band 6b) and 1788.4 - 1906.8 GHz (band 7b) obtained using the HI…
C detection of warm dark gas in diffuse clouds
W. D. Langer, T. Velusamy, J. L. Pineda +3
We present the first results of the Herschel open time key program, Galactic Observations of Terahertz C (GOT C+) survey of the [CII] fine-structure line at 1.9 THz (158 micron…
Herschel/HIFI measurements of the ortho/para ratio in water towards Sagittarius B2(M) and W31C
D. C. Lis, T. G. Phillips, P. F. Goldsmith +74
We present Herschel/HIFI observations of the fundamental rotational transitions of ortho- and para-HO and HO in absorption towards Sagittarius~B2(M) and W31C. The…
Herschel/HIFI discovery of interstellar chloronium (HCl)
D. C. Lis, J. C. Pearson, D. A. Neufeld +102
We report the first detection of chloronium, HCl, in the interstellar medium, using the HIFI instrument aboard the \emph{Herschel} Space Observatory. The li…
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…
The CHESS chemical Herschel surveys of star forming regions: Peering into the protostellar shock L1157-B1. I. Shock chemical complexity
C. Codella, B. Lefloch, C. Ceccarelli +2
We present the first results of the unbiased survey of the L1157-B1 bow shock, obtained with HIFI in the framework of the key program Chemical Herschel surveys of star forming regi…
Clouds, filaments and protostars: the Herschel Hi-GAL Milky Way
S. Molinari, B. Swinyard, J. Bally +121
We present the first results from the science demonstration phase for the Hi-GAL survey, the Herschel key-project that will map the inner Galactic Plane of the Milky Way in 5 bands…
Mission Concept for the Single Aperture Far-Infrared (SAFIR) Observatory
Dominic J. Benford, Michael J. Amato, John C. Mather +2
The Single Aperture Far-InfraRed (SAFIR) Observatory's science goals are driven by the fact that the earliest stages of almost all phenomena in the universe are shrouded in absorpt…
