Scientific paper

Galactic 'bubbles' have been shown by initial results from the Herschel Hi-GAL Survey and the Red MSX Source (RMS) Survey to be hosts to newly discovered populations of embedded young protostars.
We characterise the clump formation efficiency in several of these bubbles, and trace the indicators of triggering processes in the rims. The radial profiles of dust and gas column densities point to a 'shock-like' triggering process as a significant contributor to YSO formation. The large populations of protostars revealed by the surveys are sufficient to effectively rule out specific models of the triggering process as significant contributors to star formation in these bubbles.
