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…
Investigating high-mass star formation through maser surveys
S. P. Ellingsen, M. A. Voronkov, D. M. Cragg +3
Interstellar masers are unique probes of the environments in which they arise. In studies of high-mass star formation their primary function has been as signposts of these regions…
A Search for Propylene Oxide and Glycine in Sagittarius B2 (LMH) and Orion
M. R. Cunningham, P. A. Jones, P. D. Godfrey +17
We have used the Mopra Telescope to search for glycine and the simple chiral molecule propylene oxide in the Sgr B2 (LMH) and Orion KL, in the 3-mm band. We have not detected eithe…
Models of class II methanol masers based on improved molecular data
D. M. Cragg, A. M. Sobolev, P. D. Godfrey
The class II masers of methanol are associated with the early stages of formation of high-mass stars. Modelling of these dense, dusty environments has demonstrated that pumping by…
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…
