"The Galaxy-Dark Matter Connection"

Galaxies are believed to form and reside inside extended dark matter haloes. Consequently, the large-scale distribution of galaxies is related to that of the dark matter, albeit it in a complicated, biased way. I will present a novel technique to determine the galaxy-dark connection, and demonstrate how it can be used to constrain cosmological parameters as well as the physics of galaxy formation. I will also show how this method can be used to interpret galaxy-galaxy lensing, which is a promising new technique that can be used to directly probe the dark matter that permeates our Universe.
