Abstract: Recent observations have revealed the existence of enormously energetic ∼1061 erg active galactic nuclei outbursts in three relatively distant galaxy clusters. These outbursts have produced bubbles in the intracluster medium, apparently supported by pressure from relativistic particles and/or magnetic fields. Here, we argue that if ≥GeV particles are responsible then these particles are very likely protons and nuclei, rather than electrons, and that the γ-ray emission from these objects, arising from the interactions of these hadrons in the intracluster medium, may be marginally detectable with instruments such as the Gamma-ray Large Area Space Telescope (GLAST) and the High Energy Stereoscopic System (HESS).
