Unambiguous evidence for particle acceleration in an SNR shell
Resolved shell in VHE -rays
Close correlation between X-rays and -rays - could the VHE emission be IC?
• Hard to explain spectral shape and implied B-field is low...
X-rays: ASCA 1-3 keV (contours)
-rays: HESS (colour scale)
The SNR RX J1713.7-3946
