Description
In the last years, the observation of the Galactic plane by the third generation of
Cerenkov Telescopes, mainly done by H.E.S.S., has revealed that pulsar wind nebulae
(PWN) are the largest source class in the Galaxy. The TeV observational
characteristics of those objects can be divided into two sub-classes : the compact
and centre-filled sources, mainly associated with young pulsars, and the middle aged
ones, which present extended and offset nebulae. The very high energy emission from
PWNe gives another point of view on the underlying electron population injected by
the pulsar, and gives access to useful information such as an estimate of the
magnetic field, and also, thanks to the longer life time of the emitting electrons,
to the history of particle injection. Moreover, the increasing number of detected
PWNe enables to perform population studies, which will help to constrain the
different physical characteristics of this population.
Here, we present recent results on PWNe and discuss progresses in the understanding
of these objects, in the light of the large number of TeV detections.
