» Cosmology and the subgroups of gamma-ray bursts
Presentation duration: 20 minutes
Presenter: Attila Meszaros
There are three subgroups of the gamma-ray bursts (Horvath et al. astro-ph/1003.0632; ApJ, in press). They are defined with respect to the duration as short, intermediate and long ones. The short (Vavrek et al. 2008, MNRAS, 391, 1741) and the intermediate (Meszaros et al. 2000, ApJ, 539, 98) subgroups are dsitributed anisotropically on the sky. The consquence of these behaviour on the cosmology is discussed. It is shown that this behavior may cause the breakdown of the cosmological principle.
