Towards a complete theory of Gamma Ray Bursts
Arnon Dar, A. De Rujula
Gamma Ray Bursts (GRBs) are notorious for their diversity. Yet, they have a series of common features. The typical energy of their rays is a fraction of an MeV. The energy dist…
On the origin of X-ray Flashes
Shlomo Dado, Arnon Dar, Alvaro De Rujula
We use the cannonball (CB) model of gamma ray bursts (GRBs) and their afterglows (AGs) to analyze the observational data on X-ray flashes (XRFs) and their AGs. We show that the obs…
Cooling flows or warming rays?
Sergio Colafrancesco, Arnon Dar, Alvaro De Rujula
The radiative cooling time of the X-ray-emitting plasma near the center in many clusters of galaxies is shorter than the age of the cluster, but neither the expected large drop in…
The Supernova associated with GRB 030329
Shlomo Dado, Arnon Dar, Alvaro De Rujula
The relative proximity of the recent gamma ray burst (GRB) 030329 resulted in a large gamma-ray fluence and in the brightest-ever afterglow (AG), hours after the burst, in the radi…
What we learn from the afterglow of GRB 021211
Shlomo Dado, Arnon Dar, Alvaro De Rujula
The behaviour of the afterglow (AG) of gamma-ray bursts (GRBs) directly provides, in the cannonball (CB) model, information about the environment of their progenitor stars. The wel…
The cannonball model of gamma ray bursts
Arnon Dar
The cannonball model (CB) of gamma ray bursts (GRBs) is incredibly more successful than the standard blast-wave models (SM) of GRBs, which suffer from profound inadequacies and lim…
