Constraining the energy budget of GRB 080721
We follow the bright, highly energetic afterglow of Swift-discovered GRB 080721 at z= 2.591 out to 36 d or 3 × 10(6) s since the trigger in the optical and X-ray bands. We do not detect a break in the late-time light curve inferring a limit on the opening angle of [graphic] and setting tight constra...
