Gamma-Ray Bursts: Super-Explosions in the Universe and Related High-Energy Phenomena | | K.A. Postnov
; | | Date: |
6 Jul 2001 | | Subject: | astro-ph hep-ph | | Affiliation: | Sternberg Astronomical Institute, Moscow, Russia | | Abstract: | The recent progress in studies of gamma-ray bursts, their afterglows, and host galaxies is discussed. The emphasis is given to high-energy phenomena associated with gamma-ray burst explosions: high-energy cosmic rays, neutrinos, gravitational waves. We also show how the relativistic fireball model for GRBs can be used to constrain modern theories of large and infinite extra-dimensions. In particular, in the frame of 5D gravity with the Standard Model localized on 3D brane (Dvali et al. 2000), the very existence of relativistic fireballs of $sim 10^{53}$ ergs puts the lower bound on the quantum gravity scale $sim 0.1$ eV. | | Source: | arXiv, astro-ph/0107122 | | Services: | Forum | Review | PDF | Favorites | |
