This work investigates the dark matters structures that form on the smallest cosmological scales.
We find that the types and abundances of structures which form at approximately Earth-mass scales are very
sensitive to the nature of dark matter. We explore various candidates for dark matter and determine the
corresponding properties of small-scale structure. In particular, we discuss possibilities for indirect detection
of dark matter through small-scale structure, and comment on the potential of these methods for
discriminating between dark matter candidates. ?? 2007 Elsevier B.V. All rights reserved.
