Extreme Ultraviolet Explorer observations of clusters of galaxies: Virgo and M87

We present results of a reanalysis of archival Extreme Ultraviolet Explorer (EUVE) data of the central region of the Virgo Cluster. We employ the new analysis method developed by Bowyer, Berghofer, & Korpela and find diffuse emission reaching out to a distance of approximate to 13'. The spatial dist ribution of this flux is incompatible with a thermal plasma origin. We inve stigate whether this emission is due to inverse Compton scattering of relat ivistic electrons against the 3 K blackbody background. We show that this e mission cannot be produced by an extrapolation to lower energies of the obs erved synchrotron radio-emitting electrons, and an additional component of low-energy relativistic electrons is required. In addition to discussing th e diffuse EUV emission, we present an analysis of the EUV emission originat ing from the jet in M87.
