  • GRB 990123: Evidence that the gamma rays come from a central engine
    Fenimore, EE; Ramirez-Ruiz, E; Wu, BB (1999)
    GRB 990123 was a long, complex gamma-ray burst with an optical transient that started early within the gamma-ray phase. The peak and power-law decay of the early optical emission strongly indicate the presence of a ...
  • Temporal evolution of the pulse width in GRBs
    Ramirez-Ruiz, E; Fenimore, EE (1999)
    Many cosmological models of GRBs envision the energy source to be a cataclysmic stellar event leading to a relativistically expanding fireball. Particles are thought to be accelerated at shocks and produce nonthermal ...
