Abstract (from CDS):

BeppoSAX observed 8 times the γ-ray bright blazar PKS 0528+134 in Feb. and Mar. 1997, during a multiwavelength campaign involving EGRET, onboard CGRO, and ground based telescopes. The source was in its faintest X-ray state observed so far, with an unabsorbed [2-10]keV flux of 2.5x10–12erg/cm2/s. The spectrum can be fitted with a power law, with energy index αX=0.49±0.07 between 0.1 and 10keV. The high energy instrument PDS detected a flux in the 15-100keV band which appears disconnected from the lower X-ray energies, most likely due to a contaminating source. We consider our findings in the context of the overall spectral energy distribution and discuss their implications for synchrotron and inverse Compton models.
