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

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

Abstract
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.
