Observations of far-ultraviolet diffuse emission from the Small Magellanic Cloud.


Abstract (from CDS):

We report the first observations of far-ultraviolet (FUV: 1000-1150 Å) diffuse radiation from the Small Magellanic Cloud (SMC) using observations from the Far-Ultraviolet Spectroscopic Explorer. The strength of FUV diffuse surface brightness in the SMC ranges from the detection limit of 2000 photons/cm2/s/sr/Å to a maximum of 3x105 photons/cm2/s/sr/Å at 1004 Å. The contribution of diffuse emission to the total radiation field was found to be 34% at 1004 Å to 44% at 1117 Å with a maximum observed uncertainty of 30%. There is a striking difference between the FUV diffuse fraction from the SMC and the Large Magellanic Cloud with the SMC fraction being higher probably because of the higher dust albedo. The FUV diffuse emission correlates with Hα emission in the H II regions of the SMC.
