Description

We found that the 4/sub -/1--30 E line (36.169 GHz) of methanol (CH3OH) is a maser in Sgr B2, with an antenna temperature of up to 60 K and a velocity width of approx.10 km s-1. This maser is spatially extended with angular size of up to 90'', is distributed along the edge of H II regions, and apparently is not directly attached to star forming regions. Components with a narrow velocity width also exist. They are unresolved by our beam and have a velocity width of <1.5 km s-1
