The Cannonball Model of Gamma Ray Bursts: Spectral and Temporal Properties of the Gamma Rays
Arnon Dar, Alvaro De Rújula
Recent observations suggest that gamma ray bursts (GRBs) and their afterglows are produced by highly relativistic jets emitted in supernova explosions. We have proposed that the re…
What is the Cosmic-Ray luminosity of our Galaxy?
A. Dar, A. De Rújula
The total cosmic-ray luminosity of the Galaxy is an important constraint on models of cosmic-ray generation. The diffuse high energy -ray and radio-synchrotron emissions of the…
Is the diffuse gamma background radiation generated by galactic cosmic rays?
Arnon Dar, A. De Rújula
We explore the possibility that the diffuse gamma-ray background radiation (GBR) at high galactic latitudes could be dominated by inverse Compton scattering of cosmic ray (CR) elec…
Fat Brane Phenomena
A. De Rujula, A. Donini, M. B. Gavela +1
Gravitons could permeate extra space dimensions inaccessible to all other particles, which would be confined to ``branes''. We point out that these branes could be ``fat'' and have…
The atmospheric neutrino anomaly without maximal mixing?
A. De Rujula, M. B. Gavela, P. Hernandez
We consider a pattern of neutrino masses in which there is an approximate mass degeneracy between the two mass eigenstates most coupled to the and flavour eigenstates.…
