Gravitational Lensing in Modified Gravity and the Lensing of Merging Clusters without Dark Matter

Abstract

Gravitational lensing in a modified gravity (MOG) is derived and shown to describe lensing without postulating dark matter. The recent data for merging clusters identified with the interacting cluster 1E0657-56 is shown to be consistent with a weak lensing construction based on MOG without exotic dark matter.
