EVN observations of 6.7 GHz methanol masers from Medicina survey
M. A. Voronkov, V. I. Slysh, F. Palagi +1
We report VLBI observations of methanol masers in the brightest 5(1)-6(0) A+ transition at 6.7 GHz in NGC 281W, 18151-1208 and 19388+2357. Using the fringe rate method absolute pos…
Protoplanetary disk in V645 Cyg as seen with H2O and methanol masers
I. E. Val'tts, V. I. Slysh, M. A. Voronkov +1
Radio images of maser spots in the infrared source GL2789, connected with the young stellar object V645 Cyg, have been obtained as a result of the radio interferometric observation…
The fine spatial structure of methanol masers as an evidence in support of their connection with bipolar outflows
V. I. Slysh, I. E. Val'tts, S. V. Kalenskii
We studied class I methanol masers in the transition 7_0-6_1 A+ at the frequency 44 GHz with the VLA. The observations on the VLA were made with the angular resolution 0''.1, which…
Space-VLBI observations of OH masers
V. I. Slysh, M. A. Voronkov, I. E. Val'tts +3
We report on the first space-VLBI observations of the OH masers in two main-line OH transitions at 1665 and 1667 MHz. The observations involved the space radio telescope on board t…
