Maser action in methanol transitions
M. A. Voronkov, A. M. Sobolev, S. P. Ellingsen +2
We report the detection with the ATCA of 6.7 GHz methanol emission towards OMC-1. The source has a size between 40'' and 90'', is located to the south-east of Ori-KL and may coinci…

Methanol in W3(H2O) and Surrounding Regions
E. C. Sutton, A. M. Sobolev, S. V. Salii +3
We present the results of an interferometric study of 38 millimeter-wave lines of CH3OH in the region around the water maser source W3(H2O) and a region extending about 30" to the…

Synchrotron emission from circumstellar disks around massive stars
Yu. A. Shchekinov, A. M. Sobolev
We argue that the interaction of stellar wind with the surface of a circumstellar accretion (or protoplanetary) disk can result in the acceleration of relativistic electrons in an…
