Source Morphology:
From
Humensky (2015) via
Lemoine-Goumard (2015):
- "The case of IC 443 is one of the most exciting results on SNRs at
this ICRC. The deep observation campaign performed by VERITAS allows
the first morphological study of this middle-age remnant in
interaction with a molecular cloud, revealing a bright gamma-ray
emission at the position of the brightest maser but also some emission
throughout the entire northeast lobe (
Humensky 2015)." Interestingly Fermi-LAT
sees a very similar morphology above 5 GeV. The spectral analysis that
is going on in different regions of the remnant seems to show a harder
spectrum in the North East (where there is no interaction with the
molecular cloud) which is extremely important to constrain and probe
the environmental dependence of cosmic-ray diffusion.
Evidence for cosmic-ray acceleration in SNR:
From
Ackermann et al. (2013)
"We detected the characteristic pion-decay feature in the gamma-ray
spectra of two SNRs, IC 443 and W44, with the Fermi Large Area
Telescope. This detection provides direct evidence that cosmic-ray
protons are accelerated in SNRs."
