Query: Gamma-ray burst models with general dynamics and fits to Fermi LAT
  bursts   We present a dissipative photospheric model for gamma-ray bursts where the
usual Band peak around MeV energies arises as synchrotron emission from around
the photosphere. We treat the initial acceleration in a general way and the GeV
emission arises as the interaction of photospheric radiation and the shocked
electrons at the deceleration radius. We show some applications of this model.
