Detection of new sources of methanol emission at 95 GHz with the Mopra telescope

A southern hemisphere survey of methanol emission sources has been carried out using the Australia Telescope National Facility Mopra millimetre telesc ope. 85 sources, the majority of them masers, have been detected in the 8(0 )-7(1) A(+) transition of methanol at 95 GHz. Together with a similar north ern hemisphere survey, this completes the search for 95-GHz methanol emissi on from the Galactic plane. The previously found correlation between intens ities of methanol emission at 44 and 95 GHz is confirmed here with the larg er sample of sources. The results of large velocity gradient statistical eq uilibrium calculations confirm the classification of these sources as class I methanol masers pumped through collisional excitation.
