| Opis: | We report on the search for steady point-like sources of neutral particles around 1018 eV between 2008 and 2013
May with the scintillator SD of the Telescope Array experiment. We found overall no significant point-like excess
above 0.5 EeV in the northern sky. Subsequently, we also searched for coincidence with the Fermi bright Galactic
sources. No significant coincidence was found within the statistical uncertainty. Hence, we set an upper limit on the
neutron flux that corresponds to an averaged flux of 0.07 km−2 yr−1 for E > 1EeV in the northern sky at the 95%
confidence level. This is the most stringent flux upper limit in a northern sky survey assuming point-like sources.
The upper limit at the 95% confidence level on the neutron flux from Cygnus X-3 is also set to 0.2 km−2 yr−1 for
E > 0.5 EeV. This is an order of magnitude lower than previous flux measurements. |
