The Astrophysics of Dark Matter Detection
Presented by Annika Peter
Ohio State University

Monday, September 23, 2013
12:00 noon in 169-336

The nature of dark matter is one of the major "known unknowns" of physics of the universe. From astronomical observations, we know that dark matter exists, makes up 26% of the mass budget of the universe, clusters strongly to form the load-bearing frame of structure for galaxy formation, and hardly interacts with ordinary matter. However, this latter channel opens one window for how to detect and characterize dark matter, and a number of ground-based and space experiments are ongoing to detect dark matter via its small (but hopefully not too small!) interaction probability with ordinary matter. In this talk, I will show that our prospects for and interpretation of dark-matter particle experiments depends on the astrophysical properties of dark matter. I will discuss this in the context of several controversial topics in the dark-matter detection world.
