SUMMARY:Dark Matter Substructure in the Milky Way\, Astronomy Colloqui
 um\, Mike Kuhlen\, Institute for Advanced Study at Princeton
DESCRIPTION:It is a clear unique prediction of the cold dark matter pa
 radigm of cosmological structure formation that galaxies form hierarch
 ically and are embedded in massive\, extended dark halos teeming with 
 self-bound substructure or &quot\;subhalos&quot\;. The amount and spat
 ial distribution of subhalos around their host provide unique informat
 ion and clues on the galaxy assembly process and the nature of the dar
 k matter. I will present results from the &quot\;Via Lactea&quot\; sim
 ulations of Galactic CDM substructure\, focusing in particular on the 
 possibility of directly observing it through the detection of gamma-ra
 ys from DM annihilations in the centers of subhalos.
