We use a sample of the 13 most luminous WMAP Galactic free–free sources, responsible for 33% of the free–free emission of the Milky Way, to investigate star formation. The sample contains 40 star-forming complexes; we combine this sample with giant molecular cloud (GMC) catalogs in the literature to identify the host GMCs of 32 of the complexes. We estimate the star formation efficiency ϵGMC and star formation rate per free-fall time ϵff. We find that ϵGMC ranges from 0.002 to 0.2, with an…
