Abstract

We examine the prompt emission mechanisms that take place in Gamma-Ray Bursts (GRBs). The nature of this process is still one of the interesting puzzles in GRBs. Recent simultaneous observations of both optical and gamma-rays from 080319c, the naked eye bursts, suggested, at first, that the observed gamma-rays are Inverse Compton (IC) scattering of the optical emission. However, optical upper limits rule out this possibility for most burst and even for 080319c, whose optical emission was extremely powerful.
