11 Oct 2003 | | Journal: | Astrophys.J. 611 (2004) L77-L80 | | Subject: | astro-ph | | Abstract: | Since the discovery of the cosmological origin of GRBs there has been growing interest in using these transient events to probe the quantum gravity energy scale in the range 10^16--10^19 GeV, up to the Planck mass scale. This energy scale can manifest itself through a measurable modification in the electromagnetic radiation dispersion relation for high energy photons originating from cosmological distances. We have used data from the gamma-ray burst (GRB) of 6 December 2002 (GRB021206) to place an upper bound on the energy dispersion of the speed of light. The limit on the first-order quantum gravity effects derived from this single GRB indicate that the energy scale is in excess of 1.8x10^17 GeV. We discuss a program to further constrain the energy scale by systematically studying such GRBs. | | Source: | arXiv, astro-ph/0310307 | | Services: | Forum | Review | PDF | Favorites | |
