The Aquarius Project: Dark Matter under a Numerical Microscope
Julio Navarro
University of Victoria
In our current paradigm for the growth of structure, dark matter
halos are the basic units of non-linear structures in the present
Universe. I will report results from the latest numerical simulations
of galaxy-scale dark halos. These state-of-the-art simulations achieve
resolutions high enough that a number of previously pending questions
regarding the structure and substructure of dark matter halos can now be
addressed with confidence. Tests demonstrate detailed convergence for
(sub)structures well below a millionth the mass of the final system,
below the mass scale associated with even the faintest galaxies known.
I will discuss applications of this simulation series, such as accurate
forecasts of the expected signal both in Earth-bound experiments designed
to detect dark matter directly, and in indirect detection experiments
like Fermi which attempt to image dark matter annihilation radiation at
gamma-ray wavelengths.
