摘要
Recent observations have revealed the existence of enormously energetic similar to 10(61) 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 gamma-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).
