The purpose of this webpage is to present an introduction to the effects of gravitational lensing on the anisotropies of the Cosmic Microwave Background Radiation. Since this is a secondary effect on the anisotropy power spectrum, the presentation will assume that the reader is familiar with the basics of cosmology, the CMBR, and its anisotropies. If that's not the case, either follow the links in the last sentence or go to Wayne Hu's homepage.

For those bold enough to venture further, use the links on the left bar to navigate through the site. There's been a conscious effort to avoid using formulae in favor of phenomenological explanations, so you'll have to go to the papers in the Reference section for all of the gory details. If you're just interested in animations, images "borrowed" from other websites and the like, dive right in.
