Water, O2 and Ice in Molecular Clouds
David Hollenbach, Michael J. Kaufman, Edwin A. Bergin +1
We model the temperature and chemical structure of molecular clouds as a function of depth into the cloud, assuming a cloud of constant density n illuminated by an external FUV (6…
Detection of Extended Hot Water in the Outflow from NGC 2071
Gary J. Melnick, Volker Tolls, David A. Neufeld +5
We report the results of spectroscopic mapping observations carried out toward a ~1 min x 1 min region within the northern lobe of the outflow from NGC 2071 using the Infrared Spec…
Chemical Rates on Small Grains and PAHs: C^+ Recombination and H_2 Formation
Mark G. Wolfire, A. G. G. M. Tielens, David Hollenbach +1
We use observations of the CI, CII, HI, and H_2 column densities along lines of sight in the Galactic plane to determine the formation rate of H_2 on grains and to determine chemic…
SWAS Observations of Water in Molecular Outflows
J. Franklin, R. L. Snell, M. J. Kaufman +4
We present SWAS detections of the ground-state 1(10)-1(01) transition of o-H2O at 557 GHz in 18 molecular outflows. These results are combined with ground-based observations of the…
Spitzer IRS Observations of the Galactic Center: Shocked Gas in the Radio Arc Bubble
Janet P. Simpson, Sean W. J. Colgan, Angela S. Cotera +4
We present Spitzer IRS spectra (R ~600, 10 - 38 micron) of 38 positions in the Galactic Center (GC), all at the same Galactic longitude and spanning plus/minus 0.3 degrees in latit…
Spitzer spectral line mapping of supernova remnants: I. Basic data and principal component analysis
David A. Neufeld, David J. Hollenbach, Michael J. Kaufman +4
We report the results of spectroscopic mapping observations carried out toward small (1 x 1 arcmin) regions within the supernova remnants W44, W28, IC443, and 3C391 using the Infra…
