HIGH-ENERGY RADIATION FROM THE CENTER OF THE LOCAL SUPERCLUSTER

Evidence in X-rays, gamma rays and ultra high energy cosmic rays (UHCR ) suggests the existence of active centers in extragalactic space whic h eject high energy particles and quanta. A concentration of these hig hest energy sources in the direction of the Local Supercluster indicat es that the brightest apparent magnitude AGN's such as 3C274 (M87), 3C 273, 36279 and Markarian 421 are the only candidate sources for this r adiation. A theoretical model of mass creation in the Local Superclust er based on a Machian theory of gravitation is described as a possible mechanism for production of the high energy while at the same time al lowing the AGN's to be at the relatively close distance of the Supercl uster. The fact that infrared photons fill intergalactic space limits the distance to the UHCR sources at a little over twice the distance t o the center of the Local Supercluster strongly localizing the highest energy radiation to this relatively close distance.
