Description |
The early phases of the formation of high-mass stars is poorly understood compared to their low-mass counterparts. High-mass stars are rarer and evolve much faster compared to low-mass stars. Moreover, massive star forming regions are much more distant and are often obscured even at mid-infrared wavelengths. Consequently, high-mass protostars are best studied using sensitive observations at high angular resolution at millimetre/sub-millimetre wavelengths. In this talk, I will review work that I have been carrying out using ATLASGAL, a blind 870 micron survey of the Galactic plane, and the Arecibo survey for 6.7 GHz methanol masers, which are signposts of high-mass star formation. |
