Model of the W3(OH) environment based on data for both maser and 'quasi-thermal' methanol lines
A. M. Sobolev, E. C. Sutton, D. M. Cragg +1
In studies of the environment of massive young stellar objects, recent progress in both observations and theory allows a unified treatment of data for maser and 'quasi-thermal' lin…
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…
