Abstract
We examine the correlation between compact radio quasars (redshifts in the range z = 0.3-2.2) and the arrival direction of ultrahigh energy cosmic ray s forming clusters. Our Monte Carlo simulation reveals a statistically sign ificant correlation on the AGASA sample: the chance probability of this eff ect being less than 1%. The implications of this result on the origin of ul trahigh energy cosmic rays are discussed.
