An Elliptical Galaxy Luminosity Function and Velocity Dispersion Sample of Relevance for Gravitational Lensing Statistics
Yu-Chung N. Cheng, Lawrence M. Krauss
We have selected 42 elliptical galaxies from the literature and estimated their velocity dispersions at the effective radius ($σ_{\re}$) and at 0.54 effective radii ($\vff$). We fi…

Gravitational lensing statistics and constraints on the cosmological constant revisited
Yu-Chung N. Cheng, Lawrence M. Krauss
We re-analyze constraints on the cosmological constant that can be obtained by examining the statistics of strong gravitational lensing of distant quasars by intervening galaxies,…

Gravitational Lensing and Dark Structures
Yu-Chung N. Cheng, Lawrence M. Krauss
We examine whether a cosmologically significant distribution of dark galaxy group or cluster-sized objects can have an optical depth for multiple imaging of distant background sour…
