Quantifying dust and the ultraviolet radiation density in the local Universe.
ROWAN-ROBINSON M.
Abstract (from CDS):
Analysis of (FFIR/FUV) versus ultraviolet colour diagrams for starburst galaxies in terms of a simple screen dust model does not support a Calzetti (1997) rather than a Milky Way extinction law, though the absence of the expected strong 2200-Å feature in several galaxies with IUE spectra does show that more detailed radiative transfer models are needed - probably with nonspherical geometry.
A simple treatment in which the 100/60-µm flux ratio is used to subtract the optically thick starburst contribution to the far-infrared radiation results in lower extinction estimates for the optically thin cirrus component, with a mean E (B -V) of 0.10.
The ultraviolet luminosity density, corrected for dust extinction, is derived and a value for the local mean star formation rate inferred. This is consistent with previous estimates from ultraviolet surveys and from Hα surveys.
