“…But in reality the situation is still unclear. Newest results of the Fermi c-ray satellite of the SNR RX J1713.7-3946 [14] disfavour this scenario. Therefore, correlation studies of shell-type SNR down to their smallest structures could help to shed light unto the underlying processes.…”

a b s t r a c tThe Richardson-Lucy deconvolution algorithm was applied to astronomical images in the very high-energy regime with photon energies above 100 GeV. Through a systematic study with respect to source significance, background level and source morphology we were able to derive optimal deconvolution parameters. The results presented show that deconvolution makes it possible to study structural details well below the angular resolution of the very high-energy c-ray experiment.

“…Despite a large amount of impressive observational results (see e.g. [9,[21][22][23]), the hadronic or leptonic origin of the gamma-ray emission detected from this young (∼ 1600 yr) SNR is still debated [24][25][26][27][28][29][30]. Conversely, an hadronic origin of the gamma-ray emission detected from some very young SNRs (e.g.…”

Abstract. Galactic cosmic rays are believed to be accelerated at supernova remnant shocks. Gamma-ray observations of both supernova remnants and associated molecular clouds have been used in several occasions to test (so far quite successfully) this popular hypothesis. Despite that, a conclusive solution to the problem of cosmic ray origin is still missing, and further observational and theoretical efforts are needed. In this paper, the current status of these investigations is briefly reviewed.

“…The Fermi satellite observed several SNRs in the GeV band with high precision [13][14][15][16][17][18][19]. The γ-ray energy spectra and the coincidence with molecular clouds of several SNRs suggest that the γ-rays are most likely of a hadronic origin, although the leptonic origin is not ruled out.…”

Cosmic ray spectral hardening due to dispersion in the source injection spectra

Recent cosmic ray (CR) experiments discovered that the CR spectra experience a remarkable hardening for rigidity above several hundred GV. We propose that this is caused by the superposition of the CR energy spectra of many sources that have a dispersion in the injection spectral indices. Adopting similar parameters as those of supernova remnants derived from the Fermi γ-ray observations, we can reproduce the observational CR spectra of different species well. This may be interpreted as evidence to support the supernova remnant origin of CRs below the knee. We further propose that the same mechanism may explain the "ankle" of the ultra high energy CR spectrum.PACS numbers: 98.70. Sa,96.50.sb,98.38.Mz Introduction-Nearly 100 years after the discovery of cosmic rays by V. Hess in 1912, several basic questions on CRs, such as the source(s) and the propagation effects, are still not well understood. Precise measurements of the CR spectra and observations of high energy γ-rays and neutrinos, are of great importance to approach the answers to these fundamental questions.
