84-GHz methanol masers, their relationship to 36-GHz methanol masers and their molecular environments
Shari Breen, Yanett Contreras, Joanne Dawson +3
We present observations of the 36- (4_-1 -> 3_0E) and 84-GHz (5_-1 -> 4_0 E) class I methanol maser transitions towards a sample of 94 known class I sites. These observations resul…
The Southern HII Region Discovery Survey I: The Bright Catalog
Trey V. Wenger, John. M. Dickey, C. H. Jordan +7
The census of Galactic HII regions is vastly incomplete in the Southern sky. We use the Australia Telescope Compact Array (ATCA) to observe 4-10 GHz radio continuum and hydrogen ra…
Accurate OH maser positions II. the Galactic Center region
Hai-Hua Qiao, Andrew J. Walsh, Shari L. Breen +6
We present high spatial resolution observations of ground-state OH masers, achieved using the Australia Telescope Compact Array (ATCA). These observations were conducted towards 17…
Calibrating the HISA temperature: Measuring the temperature of the Riegel-Crutcher cloud
H. Denes, N. M. McClure-Griffiths, J. M. Dickey +2
HI self absorption (HISA) clouds are clumps of cold neutral hydrogen (HI) visible in front of warm background gas, which makes them ideal places to study the properties of the cold…
Where is OH and Does It Trace the Dark Molecular Gas (DMG)?
Di Li, Ningyu Tang, Hiep Nguyen +15
Hydroxyl (OH) is expected to be abundant in diffuse interstellar molecular gas as it forms along with under similar conditions and within a similar extinction range. We have…
