Methanol masers in environments of three massive protostars
  We present the first EVN maps of 6.7 GHz methanol masers of three high-mass protostar candidates selected from the Torun unbiased survey of the Galactic plane. A variety of linear and arc like structures was detected. A number of maser clusters with projected sizes of 20-100 AU show monotonic velocity gradients. Some of them are roughly perpendicular to the major axes of these structures and can arise behind shock fronts.
