The Vela X pulsar wind nebula through the eyes of H.E.S.S. and Suzaku

Understand

Pulsar wind nebulae (PWNe) are among the most extreme particle accelerators in galaxies, are recognized as multi-TeV electron/positron sources, and are one of the dominant classes of Galactic gamma-ray sources.

• Vela X is a nearby PWN at 290 pc from the Earth with large apparent size ($>1^\circ$).
• The H.E.S.S.
• array of imaging atmospheric Cherenkov telescopes has detected Vela X as one of the brightest known sources of TeV gamma rays.
