Recent development in the analysis techniques used by the Milagro
collaboration had resulted in the discovery of an extended TeV
gamma-ray source in the Cygnus region of the Galaxy. The new source
MGRO J2019+37 has been detected at median energies of 12 TeV. In
addition to this extended source, new TeV gamma-ray sources have been
discovered at the same median energies when more data was analy

The Galactic Plane is accessible to H.E.S.S. at longitudes up to 80
degrees through very low elevation observations.
The ability of H.E.S.S. to observe at elevations as low as 25 degrees
corresponding to an energy threshold of few TeV has been
already validated through observations of the blazar Mkn 421.
We report on H.E.S.S. data on the Galactic Plane up to the 80° longitude range
and w

We examine the impact of nonlinear diffusive shock acceleration on the TeV visibility
of SNRs. A dense molecular cloud near a SNR provides a good target for pp-collisions
leading to subsequent gamma ray emission through neutral pion decay. The intensity
and the spectral shape of this radiation is thus determined by the spectrum of
accelerated particles. This may become instrumental in distin

TeV gamma-rays can result from the photo-de-excitation of PeV cosmic ray nuclei after
their parents have undergone photo-disintegration in an environment of ultraviolet
photons. This process is proposed as a candidate explanation of the recently
discovered HESS source at the edge of Westerlund 2. The UV background
is provided by Lyman-alpha emission within the rich O and B stellar environment.

The High Energy Stereoscopic System (H.E.S.S.), located in the Khomas
Highlands of Namibia, is an array of four imaging atmospheric-Cherenkov
telescopes designed to detect gamma rays in the very high energy
(VHE; > 100 GeV) domain. Its high sensitivity and large field of view
(5 deg) make it an ideal instrument to perform a survey within the
Galactic plane for new VHE sources. Previous obse

As part of the normal operation of the Whipple 10m Gamma Ray telescope, ten
minute drift scan “zenith” runs are made each night of observation for use as
calibration. Most of the events recorded during a zenith run are due to the
background of cosmic ray showers. However, it would be possible for a hitherto
unknown source of gamma rays to drift through the field. This paper reports

Diffuse emission from the Milky Way dominates the gamma-ray sky. About 80% of
the high-energy luminosity of the Milky Way comes from processes in the
interstellar medium. The Galactic diffuse emission traces interactions of
energetic particles, primarily protons and electrons, with the interstellar gas
and radiation field, thus delivering information about cosmic-ray spectra in
distant locati
