The W49A protocluster as imaged at 1.3 mm using ALMA. Dust cores are represented by their FWHM ellipses in white and numbered in cyan for cores also detected at 3.3 cm. In magenta numbers are cores detected only in H30α, and in white numbers are non-detections at both 3.3 cm and H30α. The field of view of the VLA X band image is represented with a solid cyan line. A scale bar is shown. Zoom-ins of the three main regions of interest (W49N, W49SW and W49 outskirts) delimited by white dashed lines are shown in Figs. 2 and 3.
