Radio Emission from Supernovae
J. I. Katz
I consider radio emission from the remarkable SN1998bw. Ni-56 and Co-56 decays produce a gamma-ray flux whose Compton-scattered electrons naturally explain the observed mildly rela…
Gamma Ray Bursts vs. Afterglows
J. I. Katz
When does a GRB stop and its afterglow begin? A GRB may be defined as emission by internal shocks and its afterglow as emission by an external shock, but it is necessary to disting…
What Have We Learned From GRB Afterglows?
J. I. Katz, T. Piran
The discovery by BeppoSAX and coordinated ground-based observations of persistent X-ray, visible and radio counterparts to GRB has successfully concluded a search begin in 1973. Th…
Implications of the Visible and X-Ray Counterparts to GRB970228
J. I. Katz, T. Piran, R. Sari
The gamma-ray burst source GRB970228 has been observed after a delay of 8--12 hours in X-rays and after one day in visible and near infrared light. This marks the first detection o…
Yet Another Model of Gamma-Ray Bursts
J. I. Katz
Sari and Piran have demonstrated that the time structure of gamma-ray bursts must reflect the time structure of their energy release. A model which satisfies this condition uses th…
Single Close Encounters Do Not Make Eccentric Planetary Orbits
J. I. Katz
The recent discovery of a planet in an orbit with eccentricity around the Solar-type star 16 Cyg B, together with earlier discoveries of other planets in orbits…
