Fe b 20 06 Estimating Column Density in Molecular Clouds with FIR and Sub-mm Emission Maps

Abstract

We have used a numerical simulation of a turbulent cloud to synthesize maps of the thermal emission from dust at a variety of far-IR and sub-mm wavelengths. The average column density and external radiation field in the simulation is well matched to clouds such as Perseus and Ophiuchus. We use pairs of single-wavelength emission maps to derive the dust… (More)
