Do Gamma-ray Burst Sources Repeat?
The demonstration of repeated gamma-ray bursts from an individual source would severely constrain burst source models. Recent reports (Quashnock and Lamb 1993; Wang & Lingenfelter 1993; Ryan et al. 1994) of evidence for repetition in the first BATSE burst catalog have generated renewed interest in this issue. Here, we analyze the angular distribution of 585 bursts of the second BATSE catalog (M...

متن کاملTwo-component Jet Models of Gamma-ray Burst Sources
Recent observational and theoretical studies have raised the possibility that the collimated outflows in gamma-ray burst (GRB) sources have two distinct components: a narrow (opening half-angle θj,n), highly relativistic (initial Lorentz factor ηn & 10 ) outflow, from which the γ-ray emission originates, and a wider (θj,w . 3 θj,n), moderately relativistic (ηw ∼ 10) surrounding flow. Using a si...
متن کاملEmission Spectra from Internal Shocks in Gamma-Ray-Burst Sources
Unsteady activity of γ-ray burst sources leads to internal shocks in their emergent relativistic wind. We study the emission spectra from such shocks, assuming that they produce a power-law distribution of relativistic electrons and posses strong magnetic fields. The synchrotron radiation emitted by the accelerated electrons is Compton up-scattered multiple times by the same electrons. A substa...
متن کاملHypernova and Gamma-ray Burst Remnants as Tev Unidentified Sources
We investigate hypernova (hyper-energetic supernova) and gamma-ray burst (GRB) remnants in our Galaxy as TeV gamma-ray sources, particularly in the role of potential TeV unidentified sources, which have no clear counterpart at other wavelengths. We show that the observed bright sources in the TeV sky could be dominated by GRB/hypernova remnants, even though they are fewer than supernova remnant...
