Alternatively, the spectral softening above 2 GeV could be due to gamma-ray absorption via photon-photon pair production on the soft X-ray photon field of the host active galactic nucleus, but such an interpretation would require the dissipation region to be located very close (l~100 gravitational radii) to the black hole, which would be inconsistent with the X-ray spectrum of the source.

Thehigh-density array has threshold energy of about 2TeV. With the YangbajingAS γ array, upper limits of γ-ray fluxes from many high energy galacticcelestial objects including Crab Nebula and active galactic nuclei weremeasured at the energy around 10TeV, and the possible evidence of existing10TeV cosmic gamma ray burst was looked for. The Sun's shadow of cosmicrays has been observed and shift of the Sun's shadow resulted from the solarinterplanetary large scale magnetic field was found. And the ultra high energyspectrum of primary cosmic ray around the 'knee' was reached.
