A structured jet model with weak-scattering thermal heating in the mixed cocoon region reproduces the quasi-thermal and non-thermal spectra of GRB 090902B while broader spectra appear in strong-scattering cases.
Case study of four GRBs finds afterglow light curves shaped by ambient density, not prompt fireball composition, with cascade pairs affecting only long GRB early optical emission.
