The Australia Telescope Compact Array (ATCA) has been used to map class I methanol masers at 36 and 44 GHz in G309.38−0.13. Maser spots are found at nine locations in an area of 50 × 30 arcsec2, with both transitions reliably detected at only two locations. The brightest spot is associated with shocked gas traced by 4.5-μm emission. The data allowed us to make a serendipitous discovery of a high-velocity 36-GHz spectral feature, which is blueshifted by about 30 km s−1 from the peak…

Southern class I methanol masers at 36 and 44 GHz
The Australia Telescope Compact Array (ATCA) has been used for high angular resolution imaging of 71 southern class I methanol maser sources quasi-simultaneously at 36 and 44 GHz. The data reveal a
Discovery of a New Class I Methanol Maser Transition at 266.8 GHz
We report the detection of a new class I methanol maser candidate from the 52-41 E transition (266.8 GHz). This methanol transition has been detected toward a nearby high-mass star-forming region
New class I methanol masers
Abstract We review properties of all known collisionally pumped (class I) methanol maser series based on observations with the Australia Telescope Compact Array (ATCA) and the Mopra radio telescope.
Class I methanol masers in low-mass star-forming regions
Results of observations of Class I methanol masers in regions of low-mass star formation (MMIL) are summarized and analyzed. Four masers were detected at 44, 84, and 95 GHz towards “chemically
FIRST INTERFEROMETRIC IMAGES OF THE 36 GHz METHANOL MASERS IN THE DR21 COMPLEX
Class I methanol masers are believed to be produced in the shock-excited environment around star-forming regions. Many authors have argued that the appearance of various subsets of class I masers may
Physical characteristics of bright Class I methanol masers
Class I CH$_3$OH masers trace interstellar shocks. They have received little attention mostly as a consequence of their low luminosities; this situation has changed recently and Class I masers are
