Abstract
A search was conducted for TeV gamma-rays emitted from the direction of the ultra-high-energy cosmic ray detected by the Fly's Eye experiment with energy E similar to 3 x 10(20) eV. No enhancement was found at a level of 10(-10)gamma cm(-2) s(-1) for E > 350 GeV. A steady source of ultra-high-energy cosmic ray protons or photons would be expected to produce a gamma-ray flux above this level. An upper limit was also set for the flux of TeV gamma-rays from 3C 147, the most prominent active galactic nucleus in the error box.
