We address the important issue how the kinetic energy of collimated blast waves in AGN and GRBs is converted into radiation. It is shown that swept-up ambient matter is quickly isotropised in the blast wave frame by a relativistic two-stream instability, which provides relativistic particles in the jet without invoking any acceleration process. The fate of the blast wave and the spectral evolution of the emission of the energetic particles is therefore solely determined by the initial condition. We compare our model with existing multiwavelength data of AGN and find remarkable agreement. © 2000 American Institute of Physics.

    Gamma-ray burst (GRB) engines are probed most intimately during the prompt gamma-ray luminous phase when the expanding blast wave is closest to the explosion center. Using GRBs 990123 and 940217 as guides, we briefly review observations of high-energy emission from GRBs and summarize some...

    We investigate synchrotron emission models as the source of gamma-ray burst spectra. We show that allowing for synchrotron self absorption and a “smooth cutoff” to the electron energy distribution produces a wide range of low-energy spectral behavior. We show that there exists a...

    Gamma-ray bursts are still a puzzle. In particular, the central engine, the total energy and the very narrow distribution of peak energies challenge model builders. We consider here an extreme model of gamma-ray bursts based on highly red- and blue-shifted positron annihilation radiation. The...

    The spectra of Gamma-Ray Burst (GRB) emission have been investigated theoretically by a number of authors (e.g., [1-3]) for different versions of a general fireball-shock scenario [4,5]. However, the existing analytical works give rather coarse predictions and suffer from many uncertainties. We...
