Where (E_{52}) is the isotropic energy in (10^{52}) ergs, (n_0) is the density in cm(^{-3}), and (\Gamma) is the bulk Lorentz factor. The "upd better" version adds a derivation of this in – a miracle for timed exams. 3. The Jet Break Angle How do you tell if a GRB jet is pointed at us or slightly off-axis?
