Probing large distance higher dimensional gravity from lensing data
Abstract
The modifications induced in the standard weak-lensing formula if Newtonian gravity differs from inverse square law at large distances are studied. The possibility of putting bounds on the mass of gravitons from lensing data is explored. A bound on graviton mass, estimated to be about 100 Mpc -1 is obtained from analysis of some recent data on gravitational lensing.
