The observed properties of dark matter on Galactic scales provide a powerful test of structure formation and on the theory of Lambda-Cold Dark Matter (LCDM). In this talk I will present new results on the mapping of the observed Milky Way satellite population onto the dark matter halo population in LCDM-based theoretical models using the highest resolution numerical simulations. I will discuss...

Amplification of dark matter annihilation signal due to the small-scale clumpiness of the Galactic halo provides the unique possibility of the indirect dark matter particle identification. We describe a cosmological scenario for formation of superdense dark matter clumps from superheavy particles. As an illustrative example it is considered the case of superheavy neutralino. The small-scale...

Detecting dark matter as it streams through detectors on Earth relies on knowledge of its phase space density on a scale comparable to the size of our solar system. Numerical simulations predict that our Galactic halo contains an enormous hierarchy of substructures, streams and caustics, the remnants of the merging hierarchy that began with tiny Earth mass microhalos. If these bound or...

We study the matter distribution in and around dark halos in the standard $\Lambda$ cold dark matter ($\Lambda$CDM) universe.
We use the outputs of high resolution $N$-body simulations to compute the mean surface density profile around galactic size dark matter halos.
The result is compared with the observed surface density profile from the lensing magnification measurement of quasars in...
