Title:The Structure and Evolution of Pulsar Wind Nebulae
Abstract:
The extended nebulae formed as pulsar winds expand into their
surroundings provide information about the composition of the winds,
the injection history from the host pulsar, and the material into
which the nebulae are expanding. Observations from across the
electromagnetic spectrum provide constraints on the evolution of
the nebulae, the density and composition of the surrounding ejecta,
the geometry of the central engines, and the long-term fate of the
energetic particles produced in these systems. Here I provide a
broad overview of the structure of pulsar wind nebulae, with specific
examples from observations extending from the radio band to very
high energy gamma-rays that demonstrate our ability to constrain
the history and ultimate fate of the energy released in the spin-down
of young pulsars.
