Résumé:
Vela X is one of the nearest Pulsar Wind Nebulae (PWN) and has served as prototype for evolutionary studies. Associated with the pulsar B0833-45, Vela X has been observed at different wavelengths and in particular in and X-ray bands. The H.E.S.S. Cherenkov telescope array has observed Vela X in 2004 and 2005, discovering very high energy gamma-ray emission in this region, centered to the south of the pulsar, and contained within a region of 0.8 degrees radius. Additional observations from 2006 to 2009 allowed further investigation into the Vela X non-thermal emission. In this work the latest results on the Vela X gamma-ray emission are presented in the context of a multiwave-length analysis.
