Nature of the cosmic gamma-ray bursts (GRB) is still not clear, but there are arguments in favor of their cosmological origin with the red shifts up to 3-4. Cosmological GRB produce huge amount of energy, which is considered in the form of an expanding fireball, or rapidly (ultrarelativistically) moving cannon balls. The origin of the hard gamma radiation is usually connected with the interaction of the «ball» with the surrounding plasma. A puzzle is the hard gamma ray afterglow, which lasts much longer than the main soft GRB. To explain this phenomenon a specific distribution of matter around the source was considered.
