ArH+ and H2O+ absorption towards luminous galaxies
Arshia M. Jacob, Karl M. Menten, Friedrich Wyrowski +3
Along several sight lines within the Milky Way ArH+ has been ubiquitously detected with only one detection in extragalactic environments, namely along two sight lines in the red sh…
The chemistry of chlorine-bearing species in the diffuse interstellar medium, and new SOFIA/GREAT observations of HCl
David A. Neufeld, Helmut Wiesemeyer, Mark J. Wolfire +6
We have revisited the chemistry of chlorine-bearing species in the diffuse interstellar medium with new observations of the HCl molecular ion and new astrochemical models. Usin…
Anomalous intensities in the infrared emission of CH explained by quantum nuclear motion and electric dipole calculations
P. Bryan Changala, David A. Neufeld, Benjamin Godard
The unusual infrared emission patterns of CH, recently detected in the planetary nebula NGC 7027, are examined theoretically with high-accuracy rovibrational wavefunctions and…
Observations and analysis of CH vibrational emissions from the young, carbon-rich planetary nebula NGC 7027: a textbook example of chemical pumping
David A. Neufeld, Benjamin Godard, P. Bryan Changala +5
We discuss the detection of 14 rovibrational lines of CH, obtained with the iSHELL spectrograph on NASA's Infrared Telescope Facility (IRTF) on Maunakea. Our observations in th…
Water in star-forming regions (WISH): Physics and chemistry from clouds to disks as probed by Herschel spectroscopy
E. F. van Dishoeck, L. E. Kristensen, the WISH team
(abridged) Data and results from the WISH key program are summarized, designed to provide a legacy data set to address its physics and chemistry. WISH targeted ~80 sources along th…
