ULTRAVIOLET BACKGROUND-RADIATION AND SCATTERED-LIGHT FROM GALACTIC DUST

We study the diffuse emission in 13 far-ultraviolet images taken with the FAUST telescope in order to constrain dust-scattering parameters a nd search for extragalactic diffuse emission. The images cover more th an 600 square degrees and sample both high and low galactic latitudes. We compare the far-ultraviolet emission in these regions with 100 mu m emission as measured by the Infrared Astronomical Satellite. We comp are these 100 mu m measurements with those from the recent Diffuse Inf rared Background Experiment and find that earlier measurements of the Galactic FUV/IR ratio need substantial corrections. We interpret the F UV emission using the Jura model for the light scattered from isolated dust clouds and find values for the dust-scattering parameters in agr eement with other studies. Using other analysis techniques, we are una ble to constrain or detect significantly an extragalactic component to the diffuse far-ultraviolet emission.
