A spectacular outburst of VHE (>100 GeV) gamma-ray emission
was observed from PKS 2155-304 in 2006 with the H.E.S.S. experiment.
The VHE flux reached levels of ~20 times the Crab Nebula flux,
more that 2 orders of magnitude above typical values
observed from the object. This extremely high flux,
when coupled with the sensitivity of H.E.S.S.,
enables temporal studies of the emission
wit

Many authors have predicted very high energy (VHE; E > 100 GeV) emission from
gamma-ray bursts (GRBs) both during the prompt phase and during the multi-component
afterglow. To date however, there has been no definitive detection of such emission.
Recently, Swift made the exciting discovery that almost half of GRBs are accompanied
by one or more X-ray flares which are found to occur from severa

Major blazar flares likely result from injections of relativistic pair plasma into
the inner jets. Quantifying the jet’s basic physical parameters has been hampered by
the modest sensitivity of past observations, which has allowed only time-averaged
pictures of these rapidly changing phenomena. The capabilities of gamma-ray
observatories have dramatically improved recently with H.E.S.S. and

The MAGIC collaboration has been performing Target of Opportunity (ToO) observations
whenever alerted that known or potential very high energy gamma-ray emitting
extragalactic sources were in a high flux state in the optical, X-ray band or/and in
the TeV energy range. Here we report on triggered observations, results of the
analysis, and possible optical-TeV correlation seen in the data. Among

The "fireball model" is often invoked to explain the prompt emission from Gamma-Ray
Bursts (GRBs) as observed in the MeV energy range. In this standard model, the prompt
emission
occurs due to collisions between layers within the relativistic jet. We will present
the expected
synchroton emission from electrons accelerated through the usual Fermi mechanism,
assuming that the
distribution of

We examine the prompt and afterglow emission
within the context of the Supercritical Pile model for GRBs.
For this we have performed self-consistent calculations
by solving three time-dependent kinetic equations for protons,
electrons and photons in addition to the usual mass
and energy conservation equations. We follow the evolution
of the RBW as it sweeps up circumstellar matter and assume

Electromagnetic radiation from blazars can be observed from the radio band up to very high energy
gamma rays, with spectral energy distributions (SEDs) apparently characterized by a two-bump structure. So far,
most of the measured SEDs could be interpreted using simple leptonic origin scenarios, like Synchrotron Self-
Compton models. However, models where the gamma rays are due to accelerated
