NH_3(1_0-0_0) in the pre-stellar core L1544
P. Caselli, L. Bizzocchi, E. Keto +11
Pre-stellar cores represent the initial conditions in the process of star and planet formation, therefore it is important to study their physical and chemical structure. Because of…
Scattering from dust in molecular clouds: Constraining the dust grain size distribution through near-infrared cloudshine and infrared coreshine
M. Andersen, J. Steinacker, W-F. Thi +3
Context. The largest grains (0.5-1 micron) in the interstellar size distribution are efficient in scattering near- and mid-infrared radiation. These wavelengths are therefore parti…
Galactic cold cores II. Herschel study of the extended dust emission around the first Planck detections
M. Juvela, I. Ristorcelli, V. -M. Pelkonen +15
Within the project Galactic Cold Cores we are carrying out Herschel photometric observations of cold interstellar clouds detected with the Planck satellite. The three fields observ…
Nitrogen hydrides in the cold envelope of IRAS16293-2422
Pierre Hily-Blant, Sébastien Maret, Aurore Bacmann +4
Nitrogen is the fifth most abundant element in the Universe, yet the gas-phase chemistry of N-bearing species remains poorly understood. Nitrogen hydrides are key molecules of nitr…
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 present and future of spectral surveys with Herschel/HIFI
E. A. Bergin, T. G. Phillips, C. Comito +56
We present initial results from the Herschel GT key program: Herschel observations of EXtra-Ordinary Sources (HEXOS) and outline the promise and potential of spectral surveys with…
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…
Water vapor toward starless cores: the Herschel view
P. Caselli, E. Keto, L. Pagani +63
SWAS and Odin provided stringent upper limits on the gas phase water abundance of dark clouds (x(H2O) < 7x10^-9). We investigate the chemistry of water vapor in starless cores beyo…
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…
Direct evidence of dust growth in L183 from MIR light scattering
J. Steinacker, L. Pagani, A. Bacmann +1
Theoretical arguments suggest that dust grains should grow in the dense cold parts of molecular clouds. Evidence of larger grains has so far been gathered in near/mid infrared exti…
Odin observations of H2O in the Galactic Centre
Aa. Sandqvist, P. Bergman, J. Black
The Odin satellite has been used to detect emission and absorption in the 557-GHz H2O line in the Galactic Centre towards the Sgr A* Circumnuclear Disk (CND), and the Sgr A +20 km/…
