Gravitational Lensing Bound On The Average Redshift Of Gamma Ray Bursts In Models With Evolving Lenses
Abstract
Identification of gravitationally lensed Gamma Ray Bursts (GRBs) in the BATSE 4B catalog can be used to constrain the average redshift of the GRBs. In this paper we investigate the effect of evolving lenses on the of GRBs in different cosmological models of universe. The cosmological parameters and have an effect on the of GRBs. The other factor which can change the is the evolution of galaxies. We consider three evolutionary model of galaxies. In particular, we find that the upper limit on of GRBs is higher in evolving model of galaxies as compared to non-evolving models of galaxies.
