Deconvolution algorithms have been used successfully for optimization/restoration/deblurring of astronomical images in a variety of wavelengths, especially in the optical band (e.g., for HST). We present here an iterative Richardson-Lucy type method designed for treatment of images obtained with the H.E.S.S. array of ground-based gamma-ray telescopes. Its application to shell-type supernova remnant images yields refined details relevant for the study of correlations with other wavelengths, and hence for interpretation in terms either of hadronic or leptonic origin of the observed VHE gamma-ray emission.
The breakthrough developments of Cherenkov telescopes in the last decade have led to angular resolution of 0.1{deg} and an unprecedented sensitivity. This has allowed the current generation of Cherenkov telescopes to discover a population of supernov
If cosmic rays with energies <100 TeV originate in the galaxy and are accelerated in shock waves in shell-type supernova remnants (SNRs), gamma-rays will be produced as the result of proton and electron interactions with the local interstellar medium
The emission mechanism for hard $gamma$-ray spectra from supernova remnants (SNRs) is still a matter of debate. Recent multi-wavelength observations of TeV source HESS J1912+101 show that it is associated with an SNR with an age of $sim 100$ kyrs, ma
Compressive sampling is a new paradigm for sampling, based on sparseness of signals or signal representations. It is much less restrictive than Nyquist-Shannon sampling theory and thus explains and systematises the widespread experience that methods
Relations between radio surface brightness ($Sigma$) and diameter ($D$) of supernova remnants (SNRs) are important in astronomy. In this paper, following the work Duric & Seaquist (1986) at adiabatic phase, we carefully investigate shell-type superno
