ANISOTROPY USING THE TIBET III AIR SHOWER ARRAY",

ABSTRACT. We analyze the large-scale two-dimensional sidereal
anisotropy of multi-TeV cosmic rays (CRs) by the Tibet Air Shower
Array, with the data taken from 1999 November to 2008 December. To
explore temporal variations of the anisotropy, the data set is divided
into nine intervals, each with a time span of about one year. The
sidereal anisotropy of magnitude, about 0.1%, appears fairly stable
from year to year over the entire observation period of nine
years. This indicates that the anisotropy of TeV Galactic CRs remains
insensitive to solar activities since the observation period covers
more than half of the 23rd solar cycle.

"OBSERVATION OF TeV GAMMA RAYS FROM THE FERMI BRIGHT GALACTIC
SOURCES WITH THE TIBET AIR SHOWER ARRAY",
Astrophysical Journal Letters 709 (2010) L6-L10
M. Amenomori, et al,
ABSTRACT. Using the Tibet-III air shower array, we search for TeV γ-
rays from 27 potential Galactic sources in the early list of bright
sources obtained by the Fermi Large Area Telescope at energies above
100 MeV. Among them, we observe seven sources instead of the expected
0.61 sources at a significance of 2σ or more excess. The chance
probability from Poisson statistics would be estimated to be 3.8 ×
10?6.
If the excess distribution observed by the Tibet-III array has a
density gradient toward the Galactic plane, the expected number of
sources may be enhanced in chance association. Then, the chance
probability rises slightly, to 1.2 × 10?5, based on a simple Monte
Carlo simulation. These low chance probabilities clearly show that the
Fermi bright Galactic sources have statistically significant
correlations with TeV γ-ray excesses. We also find that all seven
sources are associated with pulsars, and six of them are coincident
with sources detected by the Milagro experiment at a significance of 3
σ or more at the representative energy of 35 TeV. The significance
maps observed by the Tibet-III air shower array around the Fermi
sources, which are coincident with the Milagro ?3σ sources, are
consistent with the Milagro observations. This is the first result of
the northern sky survey of the Fermi bright Galactic sources in the
TeV region.
