dc.description.abstractWe have used the Swedish ESO Submillimetre Telescope (SEST) to search for new classII methanol maser transitions toward the southern source G345.01+1.79. Over a period of 5days, we observed 11 known or predicted classII methanol maser transitions. Emission with the narrow line width and characteristic velocity of classII methanol masers (in this source) was detected in eight of these transitions, two of which have not previously been reported as masers. The new classII methanol maser transitions are the 13-3-12-4 E transition at 104.1GHz and the 51-42 E transition at 216.9GHz. Both of these are from transition series for which there are no previous known classII methanol maser transitions. This takes the total number of known classII methanol maser series to 10, and the total number of transitions (or transition groups) to 18. The observed 104.1GHz maser suggests the presence of two or more regions of masing gas with similar line of sight velocities, but quite different physical conditions. Although these newly discovered transitions are likely to be relatively rare, where they are observed, combined studies using the Australia Telescope Compact Array and the Atacama Large Millimeter Array offer the prospect to be able to undertake multi-transition methanol maser studies with unprecedented detail. © 2012.
