The Abundance, Ortho/Para Ratio, and Deuteration of Water in the High-Mass Star Forming Region NGC 6334 I
M. Emprechtinger, D. C. Lis, R. Rolffs +6
We present Herschel/HIFI observations of 30 transitions of water isotopologues toward the high-mass star forming region NGC 6334 I. The line profiles of H_2^{16}O, H_2^{17}O, H_2^{…
Hydrogen Fluoride in High-Mass Star-forming Regions
Martin Emprechtinger, Raquel R. Monje, Floris F. S. van der Tak +5
Hydrogen fluoride has been established to be an excellent tracer of molecular hydrogen in diffuse clouds. In denser environments, however, the HF abundance has been shown to be app…
Technology Development for the Caltech Submillimeter Observatory Balanced Receivers
J. W. Kooi, R. A. Chamberlin, R. Monje +3
The Caltech Submillimeter Observatory (CSO) is located on top of Mauna Kea, Hawaii, at an altitude of 4.2 km. The existing suite of facility heterodyne receivers covering the submi…
Discovery of Hydrogen Fluoride in the Cloverleaf Quasar at z = 2.56
R. R. Monje, T. G. Phillips, R. Peng +3
We report the first detection of hydrogen fluoride (HF) toward a high redshift quasar. Using the Caltech Submillimeter Observatory (CSO) we detect the HF J = 1 - 0 transition in ab…
Herschel observations of interstellar chloronium
David A. Neufeld, Evelyne Roueff, Ronald L. Snell +21
Using the Herschel Space Observatory's Heterodyne Instrument for the Far-Infrared (HIFI), we have observed para-chloronium (H2Cl+) toward six sources in the Galaxy. We detected int…
