  • We report on the results of an extensive monitoring campaign of the radio afterglow of GRB 970508, lasting 450 days after the burst. The spectral and temporal radio behavior indicate that the fireball has undergone a transition to subrelativistic expansion at t ~ 100 days. This allows us to perform "calorimetry" of the explosion. The derived total energy, E0 ~ 5 × 1050 ergs, is well below the ~5 × 1051 ergs inferred under the assumption of spherical symmetry from gamma-ray and early afterglow… CONTINUE READING
