A Cannonball Model of Cosmic Rays
A. De Rujula
I outline a "Cannon-Ball" model of Cosmic Rays in which their distribution in the Galaxy, their total "luminosity", the broken power-law spectra with their observed slopes, the pos…
The Discovery of a Hyperluminal Source in the Radio Afterglow of GRB 030329
Shlomo Dado, Arnon Dar, A. De Rujula
Taylor, Frail, Berger and Kulkarni have made precise VLBI measurements of the size and position of the source of the radio afterglow of GRB 030329. They report a size evolution com…
Fifty years of Yang-Mills Theories: a phenomenological point of view
Alvaro De Rujula
On the occasion of the celebration of the first half-century of Yang--Mills theories, I am contributing a personal recollection of how the subject, in its early times, confronted p…
On the Polarization of Gamma Ray Bursts and their Optical Afterglows
Shlomo Dado, Arnon Dar, A. De Rujula
The polarization of the optical afterglow (AG) of Gamma-Ray Bursts (GRBs) has only been measured in a few instances at various times after the GRB. In all cases except the best mea…
The superluminal motion of Gamma-Ray-Burst sources and the complex afterglow of GRB 030329
Shlomo Dado, Arnon Dar, A. De Rujula
The source of the very bright Gamma-Ray Burst GRB 030329 is close enough to us for there to be a hope to measure or significantly constrain its putative superluminal motion. Such a…
