Abstract:

Measurements of the Cosmic Microwave Background and the large-scale structure of the
universe have made it possible to determine with great precision the universe's inventory, as
well as properties of its initial conditions. However, there are profound questions that remain
unanswered. Cosmological observations and galaxy dynamics seem to imply that 84% of all
matter in the universe is composed of dark matter, which is not accounted for by the Standard
Model of particles. The particle nature of dark matter is one of the most intriguing puzzles of our
time. The wealth of knowledge which is and will soon be available from cosmological surveys
will reveal new information about our universe. I will discuss how we can use new and
complementary data sets to identify new physics at different scales.
