The H.E.S.S. stereoscopic Cherenkov telescope system has observed the
Crab nebula since January 2004 with the complete four telescope array.
The stable signal from this pulsar wind nebula (PWN) has been used to
verify the performance and calibration of the instrument because of its
high flux compared to the H.E.S.S sensitivity.
These observations allow us also to study the radiation mechan

The Crab is a standard calibration source for TeV gamma ray astronomy.
Its energy spectrum extends beyond 10s of TeV, however, an open question
is does the spectrum cutoff and at what energy. We present new results from
Milagro analysis of the energy spectrum of the Crab nebula up to 100 TeV
with good statistical determination. A robust algorithm was developed to
estimate the energies of gam

The deeper and more extended scan of the Galactic Plane by H.E.S.S. during 2005 and
2006 has revealed a number of new point-like as well as extended sources. We will
present and discuss cases where the VHE emission detected by HESS could be associated
to pulsar wind nebulae around young pulsars in our Galaxy.

The Crab nebula is the best known pulsar wind nebula and one of
the most energetic sources of non-thermal radiation known in our
Galaxy. It has been extensively studied over a broad range of
energies from Radio to TeV gamma-rays. However, an observational
gap in VHE-gamma-rays exists between the data available from
satellite experiments and the currently running ground based
experiments. The

The Crab Nebula has proven to be the best tool to calibrate and to characterize the
performance of a Cherenkov telescope. Scientifically, it is interesting to measure
its energy spectrum close to the Inverse-Compton peak where a deviation is expected
from the power law seen at energies above 300 GeV. Additionally, it is important to
search for pulsed emission from the Crab Pulsar at energies

Between September 2006 and January 2007 the galactic binary source LS I
+61 303 was observed at TeV energies by the VERITAS array of Cherenkov
imaging telescopes in Southern Arizona. During this time,
contemporaneous observations were taken at X-ray energies by both the
SWIFT and RXTE satellite experiments. Although the X-ray properties of
this source have been well studied in the past,

In the last two years, the MAGIC telescope has performed an observational campaign on
the X-ray binary LS I +61 303. Observations during the first year covered 6 orbital
cycles and resulted in the first detection of the source above ~200 GeV. LS I +61 303
was also found to be variable. The second campaign spanned 4 more orbital cycles,
covering orbital phases which had not been explored befor
