Abstract

Recently, Holz and Wald have presented a method for determining gravitational lensing effects in inhomogeneous universes [D.E. Holz, and R.M. Wald, Phys. Rev. D 58, 063501 (1998)]. Their use of realistic galaxy models has been limited to the singular, truncated isothermal spheres with a fixed mass. In this paper, their method is generalized to allow for matter distributions more accurately describing the actual properties of galaxies, as derived from observations and N-body simulations. This includes the density profile proposed by Navarro, Frenk and White as well as a distribution of galaxy masses.
