Abstract:
The progenitors of high-mass stars and clusters are still challenging
to recognise. Only unbiased surveys, sensitive to compact regions of
high dust column density, can unambiguously reveal such a small
population of particularly massive and cold clumps.
Here we use the ATLASGAL survey to identify a sample of candidate
progenitors of massive clusters in the inner Galaxy.
We characterise a flux limited sample of compact sources selected from
the ATLASGAL survey. Sensitive mid-infrared data at 21-24um from the
WISE and MIPSGAL surveys were explored to search for embedded objects,
and complementary spectroscopic data were used to investigate their
stability and their star formation activity.
We identify an unbiased sample of infrared-quiet massive clumps in the
Galaxy that potentially represent the earliest stages of massive
cluster formation. An important fraction of this sample consists of
sources that have not been studied in detail before. We first find
that clumps hosting more evolved embedded objects and infrared-quiet
clumps exhibit similar physical properties in terms of mass and size,
suggesting that the sources are not only capable of forming high-mass
stars, but likely also follow a single evolutionary track leading to
the formation of massive clusters. The majority of the clumps are
likely not in virial-equilibrium, suggesting collapse on the clump
scale.
