This results in massive young stellar objects (MYSOs) being relatively rare and at large distances compared to the low mass counterparts. One of the ways to identify MYSOs is through observation of the maser line of methanol at 6.7 GHz since there is strong evidence of these masers being signposts of high-mass star formation. The most sensitive survey for 6.7 GHz methanol masers to date is the Arecibo Methanol Maser Galactic Plane Survey. The physical conditions of the sources identified in the survey can be studied using spectroscopy of rotational transitions of molecules such as ammonia and methanol, both molecules being tracers of gas at high densities. In this talk, I will summarize results of observations of ammonia at 23 GHz and methanol at 96 GHz and 241 GHz towards methanol masers identified in the Arecibo methanol maser survey. |
