Radio Transients from Gamma-Ray Bursters

The rapid time variability of gamma-ray bursts implies the sources are very compact, and the peak luminosities are so high that some matter must be ejected at ultra-relativistic speeds. The very large Lorentz factors of the bulk flow are also indicated by the very broad and hard spectra. It is natural to expect that when the relativistic ejecta interact with the interstellar matter a strong synchrotron radio emission is generated, as is the case with supernova remnants and radio galaxies. We… 

The Physics of Gamma-Ray Burst Afterglows and the Nature of Their Host Galaxies

Gamma-ray bursts are brief flashes of 7-rays, discovered by the cold-war Vela satellites in the early 1970s. For over two decades the distance scale of these explosions was unknown. In the early

Very Strong TeV Emission as Gamma-Ray Burst Afterglows

Gamma-ray bursts (GRBs) and following afterglows are considered to be produced by dissipation of kinetic energy of a relativistic fireball, and the radiation process is widely believed to be

Prompt Emission of γ-Ray Bursts in the High-density Environment of Active Galactic Nucleus Accretion Disks

Long and short γ-ray bursts (GRBs) are traditionally associated with galactic environments, where circumburst densities are small or moderate (few to hundreds of protons per cubic centimeter).

Gamma-ray Bursts and Afterglow

. The origin of GRBs has been a mystery for almost 30 years. Their sources emit a huge amount of energy on short time scales, and the process involves extreme relativistic motion with a bulk Lorentz

The Evolution of Gamma-Ray Burst Remnants

The detection of the delayed emission in X-ray, optical, and radio bands, i.e., the afterglow of γ-ray bursts (GRBs), suggests that the sources of GRBs are likely to be at cosmological distances.

No Radio Afterglow from the Gamma-Ray Burst of 1997 February 28

We present radio observations of the gamma-ray burster GRB 970228 made with the Very Large Array and the Owens Valley Radio Observatory which span a range of postburst timescales from 1 to 300 days.

The Central Engine of Gamma-Ray Bursters

Cosmic gamma-ray bursts (GRBs) are thought to be created when relativistic blast waves that are powered by "central engines" emit gamma rays between 10 and 10,000 AU from where the explosive energy

Efficiency and Spectrum of Internal Gamma-Ray Burst Shocks

We present an analysis of the internal shock model of gamma-ray bursts (GRBs), where gamma-rays are produced by internal shocks within a relativistic wind. We show that observed GRB characteristics

Hydrodynamics of Gamma-Ray Burst Afterglow

The detection of delayed emission at X-ray optical and radio wavelengths (“afterglow”) following gamma-ray bursts (GRBs) suggests that the relativistic shell that emitted the initial GRB as the



1 Galactic and Extragalactic Radio Astronomy

During 1984 the following programs of research on the interstellar medium and star formation were pursued: 1. In an attempt to determine the interaction between the Sgr A molecular clouds and the

The Compton Observatory Science Workshop

The Compton Observatory Science Workshop was held in Annapolis, Maryland on September 23-25, 1991. The primary purpose of the workshop was to provide a forum for the exchange of ideas and information
