Description
The Vela SNR region is a bright, nearby and complex region of non-thermal emission which at its centre it contains a powerful pulsar and its associated pulsar wind nebula, commonly known as Vela X. Due to its nature as one of the most local cosmic ray accelerators it has been an object of interest for many studies at the highest energies.
We present a new detailed study of VHE gamma-ray emission in the Vela X region using over 200 hours of observations from the H.E.S.S. array of imaging atmospheric Cherenkov telescopes. This rich dataset allows us for the first time to study and observe changes in the gamma-ray spectral properties across the Vela X region, in particular measuring a lower energy cutoff in the diffuse region surrounding the central PWN. H.E.S.S. results are combined with multi-wavelength observations, most importantly X-ray observations from eROSITA to allow a detailed insight into particle acceleration and propagation within this nearby energetic region.
