The distribution of γ‐ray bursts as observed by BATSE rules out the galactic disk origin, and it is consistent with the cosmological origin. Much work is currently done to reconcile galactic halo distribution with the absence of dipole and quadrupole moments in the positions of BATSE bursts. A relativistic expansion of the source is implied by both the

Space Science Reviews, 1983
The observational characteristics of gamma-ray bursts are reviewed, concerning their spectra as well as their temporal structure and spatial distribution. From this data, it is suggested that the sources belong to a thick halo population (scale height > 3 kpc), and that the mean recurrence time for one source is greater than 5 yr.

AIP Conference Proceedings, 1983
The time histories, size spectrum, spatial distribution, and repetition rates of gamma ray bursts are reviewed briefly. Evidence for a neutron star origin for gamma ray bursts may be found in many of these aspects of bursters. New results from optical searches are described.

We summarize the observed features of γ-ray bursts, with particular emphasis on the cyclotron lines seen in their spectra. We then discuss the theory of cyclotron resonant scattering, and compare the theoretical and observed line spectra. Finally, we mention some implications.

Gamma-ray bursts are one of the top unsolved mysteries in astrophysics, alongside such burning issues as the nature of dark matter and the cosmological constant. We have known of the existence of gamma-ray bursts for over 25 years, but these short flashes of gamma rays have defied all our attempts to understand their causes and origin.

Historical developments in the field of gamma-ray bursts are briefly reviewed. Both observational and theoretical progresses are discussed. Steps toward measuring the distances of γ-ray bursts, toward building the standard fireball internal-external shock model, are discussed in some detail.

Gamma-Ray Bursts (GRBs) are the most relativistic objects discovered so far. I describe here two aspects of the relativistic nature of GRBs. Their likely association with the formation of black holes and their possible role as sources of gravitational radiation.
