We searched for gamma-ray sources in the EGRET data from cycle 1 to cycle 9. We used
a 2D maximum likelihood method similar to that developed for the Egret 3EG catalog.
Two interstellar background models, due to cosmic-ray interactions in the Milky Way,
were used: a model where the most recent HI, CO, and inverse Compton maps were
linearly fitted to the EGRET gamma rays and a model obtained fr

Milagro is a TeV gamma-ray observatory with a ~2 sr field of view and a >90% duty
factor. The large field of view and long observation time make Milagro ideal for
surveying large regions of the Northern Hemisphere sky. A previous all-sky survey
searched for point sources (Atkins, R, et al., 2004, ApJ, 608, 680-685), but the
analysis is easily adaptable to look for intermediate-scale (~10 deg

Recent results from the HESS gamma-ray telescope have shown the presence of both
a diffuse, extended flux of gamma rays above ~0.4 TeV and discrete sources in and
near the Galactic Centre. Here, we put forward a possible explanation in terms of the
diffusion of cosmic-ray protons from a succession of supernova remnants ( SNR ) in
the SgrA* region of the Galaxy plus a probable contribution from

The detection of TeV gamma-rays from the direction of the Galactic Centre is one of
the most exciting discoveries in recent years. Observations by the H.E.S.S. system of
imaging atmospheric Cherenkov telescopes provide the most precise available data on
this source in the energy range 150 GeV - 30 TeV. The vicinity of the kinetic centre
of our galaxy harbours numerous objects which could poten

Diffuse gamma radiation produced in the interaction of cosmic-ray
particles with matter and radiation in the Galaxy can be used for
probing the origin of cosmic rays. The large field of view and
long observation time of the Milagro Gamma-Ray Observatory-- a water
Cherenkov detector that operates continuously, detecting extensive air
showers from the overhead sky -- is an ideal instrument f

The rapidly varying non-thermal X-ray emission observed from Sgr A* points to
particle acceleration taking place close to the supermassive black hole. The TeV
gamma-ray source HESS J1745-290 is coincident with Sgr A* and may be closely related
to the X-ray emission. Simultaneous X-ray and TeV observations are required to
elucidate the relationship between these two objects. Here we report on j

Recent all-sky surveys by the Tibet AS and the MILAGRO Observatories have
identified several new potential TeV Gamma-Ray sources.One of these sources
(MGRO J2019+37) is positionally coincident with a Pulsar Wind Nebula
G75.1+0.1, ,and the second source (MGRO J1909+06) is nearby the Supernova
Remnant G40.5-0.5. MGRO J2019+37 was observed by the VERITAS
Observatory during November 2006, a
