Description
GRBs have been found within a wide range of power and photon energy spectra. Their understanding was usually seen as the largest explosion, fireball, billion times a SN one. Fireball, by definition were isotropic. Last decades have been an evolution of fire-ball hitting shells in some fountain of tens degree size. I advocated since 1998 a much thinner jet whose solid angle is a part of a billion: it is blazing at SN output while in axis appear as a GRB output. Its spread precessing, bending and blazing leads to high variability, gamma photons at high energy and long life. As in GRB130427A event.
