Gamma-ray bursts (GRBs) have been detected up to GeV energies and are
predicted by many models to emit in the very high energy (VHE, >100 GeV)
regime too. Detection of such emission would allow us to constrain GRB
models. Since its launch, in late 2004, the Swift satellite has been
locating GRBs at a rate of approximately 100 per year. The rapid
localization and follow-up in many wavelengths

The giant radio galaxy M87 was observed at GeV/TeV gamma-ray energies with the
H.E.S.S. (High Energy Stereoscopic System) Cherenkov telescopes in the years
2003-2006. The observations confirm M87 as the first extragalactic TeV gamma-ray
source not of the blazar type (first indications of a signal were reported by the
HEGRA collaboration earlier). The TeV gamma-ray flux from M87 as measured wit

The GLAST Large Area Telescope (LAT) is the next generation satellite experiment for
high-energy gamma-ray astronomy. It is a pair conversion telescope built with a
plastic anticoincidence shield, a segmented CsI electromagnetic calorimeter, and the
largest silicon strip tracker ever built. It will cover the energy range from 20 MeV
to more than 300 GeV, shedding light on many issues left open

The star and galaxy formation history has left an imprint on the diffuse
extragalactic radiation field in the ultraviolet to infrared wavelength regime. In
the spectral energy distribution two distinct bumps
are expected: A first bump in the optical to near-infrared coming from direct
starlight redshifted
over time and a second bump in the infrared from dust-reemission. Direct measurements

M87 is the only non-blazar AGN to be discovered emitting VHE gamma rays, and so it
represents a unique opportunity to study the phenomena of gamma ray emission from
AGN. The rapid variability and unexpectedly hard TeV energy spectrum of M87 has
recently been reported by the HESS collaboration. With VERITAS beginning initial
science observations in early 2007, M87 is a prime target for observat

Opacity effects in relativistic sources of high-energy gamma-rays,
such as gamma-ray bursts (GRBs) or Blazars, can probe the Lorentz
factor of the outflow as well as the distance of the emission site
from the source, and thus help constrain the composition of the
outflow (protons, pairs, magnetic field) and the emission
mechanism. The attenuation of high energy photons will be probed by
the

The wide-band all-sky monitor (WAM) is the secondary function
of large lateral BGO shield of the Hard X-ray Detector (HXD) onboard
the Suzaku mission. Owing to its large geometrical area of 800 cm2 per
side and wide-field of view, the WAM is very suitable to observe gamma-ray
bursts (GRBs) in the energy range of 50--5000 keV. It has actually
observed 183 GRBs confirmed by other satellit
