Resolving the 'missing satellites problem'
by Andrey Kravtsov
A generic prediction of the standard galaxy formation paradigm is that dark matter halos are "lumpy", filled with hundreds of dense, gravitationally bound clumps of dark matter. The abundance of these clumps is much larger than the typical number of dwarf satellites around galactic halos --- the discrepancy often called "the missing satellites problem". KICP member Andrey Kravtsov and his collaborators proposed a solution to the missing satellites problem based on the observations that dwarf galaxy size objects in numerical simulations often undergo dramatic mass evolution.
