The water abundance behind interstellar shocks: results from /PACS and /IRS observations of HO, CO, and H
David A. Neufeld, Antoine Gusdorf, Rolf Güsten +7
We have investigated the water abundance in shock-heated molecular gas, making use of measurements of far-infrared CO and HO line emissions in combination with $Spit…
Interstellar water chemistry: from laboratory to observations
Ewine F. van Dishoeck, Eric Herbst, David A. Neufeld
Water is observed throughout the universe, from diffuse interstellar clouds to protoplanetary disks around young stars, and from comets in our own solar system and exoplanetary atm…
Far-Infrared Spectroscopy of the Galactic Center. Hot Molecular Gas: Shocks versus Radiation near SgrA*
Javier R. Goicoechea, M. Etxaluze, J. Cernicharo +10
We present a 52-671um spectral scan toward SgrA* taken with the PACS and SPIRE spectrometers onboard Herschel. The achieved angular resolution allows us to separate, for the first…
Herschel/HIFI observations of a new interstellar water maser: the 5(32)-4(41) transition at 620.701 GHz
David A. Neufeld, Yuanwei Wu, Alex Kraus +4
Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared (HIFI), we have performed mapping observations of the 620.701 GHz 5(32)-4(41) transition of ortho-…
Hydrogen chloride in diffuse interstellar clouds along the line of sight to W31C (G10.6-0.4)
R. R. Monje, D. C. Lis, E. Roueff +5
We report the detection of hydrogen chloride, HCl, in diffuse molecular clouds on the line of sight towards the star-forming region W31C (G10.6-0.4). The J = 1-0 lines of the two s…
Herschel/HIFI search for H2-17O and H2-18O in IRC+10216: constraints on models for the origin of water vapor
David A. Neufeld, Volker Tolls, Marcelino Agúndez +7
We report the results of a sensitive search for the minor isotopologues of water, H2-17O and H2-18O, toward the carbon-rich AGB star IRC+10216 (a.k.a. CW Leonis) using the HIFI ins…
Direct Determination of the HF/H2 Abundance Ratio in Interstellar Gas
Nick Indriolo, D. A. Neufeld, A. Seifahrt +1
We report the first detection of the v=1--0, R(0) ro-vibrational transition of HF at 2.499385 microns arising from interstellar gas. The line is seen in absorption toward 3 backgro…
