Abstract:
Supernova remnants exhibit shock fronts (shells) that can accelerate
charged particles up to very high energies. In the past decade,
measurements of a handful of shell-type supernova remnants in very
high-energy gamma rays have provided unique insights into the
acceleration process. Among those objects, RX J1713.7-3946 (also known
as G347.3-0.5) has the largest surface brightness, allowing us in the
past to perform the most comprehensive study of morphology and
spatially resolved spectra of any such very high-energy gamma-ray
source. Here we present extensive new H.E.S.S. measurements of RX
J1713.7-3946, almost doubling the observation time compared to our
previous publication. Combined with new improved analysis tools, the
previous sensitivity is more than doubled. The H.E.S.S. angular
resolution of 0.048° (0.036° above 2TeV) is unprecedented in
gamma-ray astronomy and probes physical scales of 0.8 (0.6) parsec at
the remnant's location. The new H.E.S.S. image of RX J1713.7-3946
allows us to reveal clear morphological differences between X-rays and
gamma rays. In particular, for the outer edge of the brightest shell
region, we find the first ever indication for particles in the process
of leaving the acceleration shock region. By studying the broadband
energy spectrum, we furthermore extract properties of the parent
particle populations, providing new input to the discussion of the
leptonic or hadronic nature of the gamma-ray emission mechanism.
