Title: Unveiling of the Relationship Between Luminous and Dark Matter

We have known for 70 years that the matter density and dynamics of the universe are dominated by invisible dark matter. Unfortunately we can only 'observe' dark matter where luminous tracers exist. Thmore »is has made it impossible for us to determine directly how much dark matter there is and how it is distributed. Gravitational lensing provides the first opportunity to evade these limitations in a serious way. I will discuss a variety of lensing effects, then describe some ways in which we use lensing in the Sloan Digital Sky Survey to probe the relationship between luminous and dark matter. Our SDSS lensing measurements enable a variety of really new studies, in areas as disparate as galaxy formation and the matter density of the Universe.« less
