Soft X-rays from the Large Magellanic Cloud: implications on the origin of the diffuse X-ray background.
Abstract
A total soft X-ray luminosity of approximately 10 to the 38th power ergs/s was observed from the Large Magellanic Cloud (LMC) during pointed rocket observations in November 1973. Simple spectral parameters are derived and discussed. Upper limits at 1 KeV to several known LMC point sources are presented. A diffuse bar source reported previously was not detected. Strong limits are placed on the fraction of halo and extragalactic diffuse X-ray flux observed in the direction of the LMC due to the lack of correlation of the 0.25-KeV diffuse flux with interstellar hydrogen in the Galaxy and in the LMC.
