Dark Matter Mysteries and Galaxy Evolution – Dr. Tommaso Treu

(March 15, 2011)  According to our current understanding, most of the mass of the universe is in the form of a mysterious substance, known as dark matter, that does not emit or absorb light. We do not know what dark matter is made of, but we see it manifest itself at astronomical scales through its gravitational effects. Although the cosmological model based on dark matter works quite well on very large scales, there appears to be tension at subgalactic scales, where dark matter interacts with regular matter. Professor Treu will present his research on this shadowy component of the cosmos and discuss some intriguing questions in dark matter cosmology.
