Far-ultraviolet Diffuse Emission from the Large Magellanic Cloud
Abstract
We present the first observations of diffuse radiation in the far-ultraviolet (FUV; 1000-1150 Å) from the Large Magellanic Cloud based on observations made with the Far Ultraviolet Spectroscopic Explorer. The fraction of the total radiation in the field emitted as diffuse radiation is typically 5%-20% with a high of 45% near N70 where there are few exciting stars, indicating that much of the emission is not due to nearby stars. Much less light is scattered in the FUV than at longer wavelengths, with the stellar radiation going into heating the interstellar dust.
