Terahertz Water Masers: II. Further SOFIA/GREAT Detections toward Circumstellar Outflows, and a Multitransition Analysis
David A. Neufeld, Karl M. Menten, Carlos Durán +8
Following up on our discovery of terahertz water masers, reported in 2017, we report two further detections of water maser emission at frequencies above 1 THz. Using the GREAT inst…
Extending the view of ArH+ chemistry in diffuse clouds
Arshia M. Jacob, Karl M. Menten, Friedrich Wyrowski +2
One of the surprises of the Herschel mission was the detection of ArH+ towards the Crab Nebula in emission and in absorption towards strong Galactic background sources. Although th…
High Resolution Infrared Spectroscopy of Hot Molecular Gas in AFGL 2591 and AFGL 2136: Accretion in the Inner Regions of Disks Around Massive Young Stellar Objects
Andrew G. Barr, Adwin Boogert, Curtis N. DeWitt +8
We have performed a high resolution 4-13 spectral survey of the hot molecular gas associated with the massive protostars AFGL 2591 and AFGL 2136, utilising the Echelon-Cross-E…
Distribution of Water Vapor in Molecular Clouds. II
Gary J. Melnick, Volker Tolls, Ronald L. Snell +8
The depth-dependent abundance of both gas-phase and solid-state water within dense, quiescent, molecular clouds is important to both the cloud chemistry and gas cooling. Where wate…
Detection of vibrational emissions from the helium hydride ion (HeH) in the planetary nebula NGC 7027
David A. Neufeld, Miwa Goto, T. R. Geballe +3
We report the detection of emission in the v=1-0 P(1) (3.51629 micron) and P(2) (3.60776 micron) rovibrational lines of the helium hydride cation (HeH+) from the planetary nebula N…
