Constraining the intrinsic energy of GRB events
arXiv:1306.0829
Abstract
Considering a GRB event as a relativistic ejecta where the relativistic moving makes radiation become anisotropic, we are able to show that the required intrinsic energy associated with these events is significantly smaller than those values commonly presented in literature for an isotropic distribution of emitted energy. Our results show energy values around ergs for Lorentz factor and around ergs for , values which are more compatible with energies involved in AGN events rather than those related to the formation of stellar black holes and hypernovas.
