Low-Luminosity  Gamma-Ray Bursts could be the candidate sources of ultra-high-energy  cosmic-ray heavy nuclei, which are accelerated in the shock. High-energy  photons emitted from these nuclei through photodisintegration process  provide indirect evidence for nuclei’s acceleration. We model the  photodisintegration-induced TeV photon emission from low-luminosity  gamma-ray bursts and discuss the detectability by the high-energy  observatories such as Fermi, H.E.S.S and CTA etc.

Upper panel:  UVOT and XRT afterglows of GRB060218/SN2006aj observed by the Swift  satellite. The “SN” denotes the supernova light curve at tens of days.  Lower panel: the multi wave band emission of SN2006aj by placing it at a  distance of 10kpc. The work by LIU Xuewen ，WU Xuefeng，has been accepted  to be published in ASTRONOMICAL JOURNAL 2012 .Vol.143. No.5 .pp.115
