The Dark Matter Annihilation Signal from Dwarf Galaxies and Subhalos

Table 1

The properties of likely DM subhalos of the 18 Milky Way dSph galaxies for which values (column 3) have been published [33]. and are the maximum circular velocity and its radius, and the largest a subhalo ever acquired and its corresponding radius. The first number is the median over all Via Lactea II subhalos matching the dSph's distance and , the numbers in parentheses the 16th and 84th percentiles (see text for details).
