A northern sky survey for TeV gamma-ray steady point sources using the Tibet-III air shower array

抄録

The Tibet III air shower array, located at 4,300 m above sea level, Tibet, China, has a wide field of view and a high duty cycle. Results on TeV gamma-ray point source search using data taken from the Tibet-III (1999 November - 2010 May) array are presented. The event statistics employed in this analysis is approximately four times more than that used in our previously published results. The result shows the directions of the Crab and Mrk421 have excess of the number of the air shower events. The shape of the significance distributions from all surveyed directions is influcenced not only by the excess of the gamma-ray events from Crab and Mrk421 but also by the excess of air shower events from the Cygnus region and the Tail-in region. In the previous survey paper, the high significance value of each prominent directions except for the Crab, Mrk 421, Tail-in region and J1908+06 can be explained by the statistical fluctuations.
