Weak-Scale Hidden Sector and Fireball Models of Gamma-Ray Bursts
The annihilation of pairs of very weakly interacting particles in the neibourghood of gamma-ray sources is introduced here as a plausible mechanism to avoid the baryon load problem. This way we can explain how these very high energy gamma-ray bursts can be powered at the onset of very energetic events like supernovae explosions. Our approach uses the weak-scale hidden sector models in which the...
متن کاملCan Fireball Models Explain Gamma Ray Bursts?
The observed afterglows of gamma ray bursts, in particular that of GRB 970228 six months later, rule out spherical explosions powered by mergers or accretion induced collapse of compact stellar objects in galaxies as the origin of Gamma Ray Bursts. They can be produced by superluminal jets from such sources.
متن کاملFireball and Cannonball Models of Gamma-Ray Bursts Confront Observations
The two leading contenders for the theory of gamma-ray bursts (GRBs) and their afterglows, the Fireball and Cannonball models, are compared and their predictions are confronted, within space limitations, with key observations, including recent observations with SWIFT.
متن کاملGamma-ray Bursts and the Fireball Model
Gamma-ray bursts (GRBs) have puzzled astronomers since their accidental discovery in the late sixties. The BATSE detector on the COMPTON-GRO satellite has been detecting one burst per day for the last six years. Its findings have revolutionized our ideas about the nature of these objects. They have shown that GRBs are at cosmological distances. This idea was accepted with difficulties at first....
متن کاملCan Fireball or Firecone Models Explain Gamma Ray Bursts?
The observed afterglows of gamma ray bursts (GRBs), in particular that of GRB 970228 six months later, seem to rule out relativistic fireballs and relativistic firecones driven by merger or accretion induced collapse of compact stellar objects in galaxies as the origin of GRBs. GRBs can be produced by superluminal jets from such events.
