Beschreibungen/Notizen

• We searched for steady PeV gamma-ray emission from the Monogem ring region with the Tibet air shower array from 1997 February to 2004 October. No evidence for statistically significant gamma-ray signals was found in a region 111 , R.A. < 114, 12.5 , decl. < 15.5 in the Monogem ring where the MAKET-ANI experiment recently claimed a positive detection of PeV high-energy cosmic radiation, although our flux sensitivity is approximately 10 times better than MAKET-ANI's. We set the most stringent integral flux upper limit at a 99% confidence level of 4.0 x 10 super(-12) cm super(-2) s super(-1) sr super(-1) above 1 PeV on diffuse gamma rays extended in the 3 x 3 region.
