Talk Outline

Precursors of rich stellar clusters are now being explored with an unprecedented detail using the Atacama Large Millimeter/submillimeter Array. I will present results from the SPARKS and ALMA-IMF observing programmes that reveal a large number of protostellar cores in massive Galactic clumps. Spectroscopic observations are used to characterise these protostellar cores in a greater detail and infer the physical conditions of the collapsing gas. I will also present our results using molecular line emission to dissect high-mass protostellar cores that allowed us to pinpoint, for the first time, accretion shocks around a high-mass protostar.
