Core mass function across galactic env. III.

It may be inherited from the core mass function (CMF) or arise as a result of more chaotic, competitive accretion. Dense, gravitationally bound cores are seen in molecular clouds and some observations have suggested that the CMF is similar in shape to the IMF, though translated to higher masses by a factor of ~3.

Here we measure the CMF in 28 dense clumps within 3.5kpc that are likely to be central regions of massive protoclusters, observed via 1.3mm dust continuum emission by the ALMAGAL project. We identify 222 cores using the dendrogram algorithm with masses ranging from 0.04 to 252M_{sun}_. We apply completeness corrections for flux and number recovery, estimated from core insertion and recovery experiments.
