How do methanol masers manage to appear in the youngest star vicinities and isolated molecular clumps?
A. M. Sobolev, D. M. Cragg, S. P. Ellingsen +10
General characteristics of methanol (CH3OH) maser emission are summarized. It is shown that methanol maser sources are concentrated in the spiral arms. Most of the methanol maser s…
The Australia Telescope campaign to study southern class I methanol masers
M. A. Voronkov, K. J. Brooks, A. M. Sobolev +3
The Australia Telescope Compact Array (ATCA) and the Mopra facility have been used to search for new southern class I methanol masers at 9.9, 25 (J=5) and 104 GHz, which are though…
Class I methanol masers in the outflow of IRAS 16547-4247
M. A. Voronkov, K. J. Brooks, A. M. Sobolev +3
The Australia Telescope Compact Array (ATCA) has been used to image class I methanol masers at 9.9, 25 (a series from J=2 to J=9), 84, 95 and 104 GHz located in the vicinity of IRA…
Discovery of new 19.9-GHz methanol masers in star forming regions
S. P. Ellingsen, D. M. Cragg, J. E. J. Lovell +3
We have used the NASA Tidbinbilla 70-m antenna to search for emission from the 2(1)-3(0)E 19.9-GHz transition of methanol. The search was targeted towards 22 star formation regions…
Masers and Outflows in the W3(OH)/W3(H2O) region
A. M. Sobolev, E. C. Sutton, D. M. Cragg +5
Methanol masers and molecular shock tracers were observed in the W3(OH)/W3(HO) region with the BIMA array and the Onsala 20m radiotelescope. Characteristics of the outflows in…
Search for class II methanol masers at 23.1 GHz
D. M. Cragg, A. M. Sobolev, J. L. Caswell +2
In the early days of methanol maser discoveries the 9(2)-10(1) A+ transition at 23.1 GHz was found to exhibit maser characteristics in the northern star-forming region W3(OH), and…
