Apparent growth in output and hardness of GRB with redshift: The legacy of a persisten thin precessing gamma Jet |
|
Abstract |
The Gamma ray burst output in the Universe seem to grow with their redshift. The GRB (as all sources) are more and more abundant with their distance; A more abundant sample of thin jets, whose inner gamma cone jet is more hard and rare to be aligned may explain the higher output and the higher gamma hardness. The persistent and precessing gamma jet, powered by twin lepton jet in synchrotron radiation, may explain this apparent paradox while combining several (eight-nine) order of magnitude spread in GRB powers between near and far cosmic edges.
