The American Astronomical SocietyWe present the results of a search for cosmic-ray point sources at energies in excess of 4.0 × 1019 eV in the combined data sets recorded by the Akeno Giant Air Shower Array and High Resolution Fly's Eye stereo experiments. The analysis is based on a maximum likelihood ratio test using the probability density function for each event rather than requiring an a priori choice of a fixed angular bin size. No statistically significant clustering of events consistent with a point source is found.enSearch for point sources of ultra-high-energy cosmic rays above 4.0 x 1019 eV using a maximum likelihood ratio testJournal article002005020110.1086/4285700002281977000162-s2.0-2014438301455227Bellido Caceres, J.
