The ATLASGAL survey: pinning down the earliest stages of high-mass star-formation Timea Csengeri MPIfR, Bonn, DE
The ATLASGAL survey is one of the most sensitive and extensive ground-based survey of the inner Galaxy at sub-millimeter wavelengths providing an unprecedented view on all stages of massive star-formation. With over 10 000 compact sources identified, it provides a statistically significant sample of massive star-forming clumps, many of them have been previously not known. I will present recent results from ATLASGAL with particular focus on how complementing the cold dust emission with sensitive mid-IR surveys was used to identify a sample of massive clumps with extreme youth. Spectroscopic follow-up observations of this sample confirm intensive outflows associated with potentially young, Class 0 like embedded protostars. Such a Galactic scale sample is the first step to characterize the initial conditions of high-mass star-formation.
