  6. Various viewpoints/problems ……………………………… for “further promoting discussions” ○ Prospect for HE gamma-ray astrophysics what lacks now and what will be provided by CTA with improved sensitivity ? Hadronic emission of gamma-rays ? (γ, ν have common origin) • point-like object of • emitting neutrino ○ Diffuse or Point-like (discrete) emission ? How to confirm “point-like neutrino source” ? How far distances HE neutrinos come from? • intensity of diffuse neutrino • size of universe ○ Multi-messenger detection, following the “alarm” of Flare, transient event : sufficient /detectable intensity from “Stable emission” ? • Cascade process • in extragalactic space ○ Prospect for UHE cosmic rays particle interaction, beyond 1020eV up to “Planck energy”? effect of GZK cutoff --- diffuse γ and ν? Cowork with γ and ν? • Planck energy • Ep = (hc5/2πG)0.5 • = 1.2x1028eV
