The volume densities of giant molecular clouds in M 83
The volume densities of giant molecular clouds in M 83
Using observed GALEX far-ultraviolet (FUV) fluxes and VLA images of the 21-cm HI column densities, along with estimates of the local dust abundances, we measure the volume densities of a sample of actively star-forming giant molecular clouds (GMCs) in the nearby spiral galaxy M 83 on a typical resolution scale …
