Low Frequency Radio Pulses from Gamma-Ray Bursts?
Vladimir V. Usov, Jonathan I. Katz
Gamma-ray bursts, if they are generated in the process of interaction between relativistic strongly magnetized winds and an ambient medium, may be accompanied by very short pulses…
Compton Electrons and Electromagnetic Pulse in Supernovae and Gamma-Ray Bursts
J. I. Katz
When gamma-rays emerge from a central source they may undergo Compton scattering in surrounding matter. The resulting Compton-scattered electrons radiate. Coherent radiation by suc…
After HETE
J. I. Katz
The outstanding task of gamma-ray burst astronomy is to test the hypothesis that they are at cosmological distances. This can be done by determining the coordinates of at least a f…
A Precessing Disc in OJ287?
J. I. Katz
Sillanpää, {\it et al.} (1996) have demonstrated that the AGN OJ287 has intensity peaks which recur with a period of about 12 years. I suggest that this is the result of the sweepi…
Two Classes of Gamma-Ray Bursts
J. I. Katz, L. M. Canel
Data from the 3B Catalogue suggest that short and long GRB are the results of different classes of events, rather than different parameter values within a single class: Short burst…
The Eddington Limit and Soft Gamma Repeaters
J. I. Katz
Observed intensities and inferred distances of soft gamma repeaters imply luminosities in excess of the nominal (electron-scattering opacity) Eddington limit by four to six orders…
