Statistics of Gravitational Microlensing Magnification. II. Three-Dimensional Lens Distribution
Man Hoi Lee, Arif Babul, Lev Kofman +1
In Paper I we studied the theory of gravitational microlensing for a planar distribution of point masses. In this second paper, we extend the analysis to a three-dimensional lens d…

Statistics of Gravitational Microlensing Magnification. I. Two-Dimensional Lens Distribution
Lev Kofman, Nick Kaiser, Man Hoi Lee +1
(Abridged) In this paper we refine the theory of microlensing for a planar distribution of point masses. We derive the macroimage magnification distribution P(A) at high magnificat…

A Weak Gravitational Lensing and X-ray Analysis of Abell 2163
G. Squires, D. M. Neumann, N. Kaiser +5
We report on the detection of dark matter in the cluster of galaxies Abell~2163 using the weak gravitational distortion of background galaxies, and an analysis of the cluster X-ray…
