Query: Searching for Dark Matter Sub-structure with HAWC   Simulations of dark matter show a discrepancy between the expected number of
Galactic dark matter sub-halos and how many have been optically observed. Some
of these unseen satellites may exist as dark dwarf galaxies: sub-halos like
dwarf galaxies with no luminous counterpart. Assuming WIMP dark matter, it may
be possible to detect these unseen sub-halos from gamma-ray signals originating
from dark matter annihilation. The High Altitude Water Cherenkov Observatory
(HAWC) is a very high energy (500 GeV to 100 TeV) gamma ray detector with a
wide field-of-view and near continuous duty cycle, making HAWC ideal for
unbiased sky surveys. We perform such a search for gamma ray signals from dark
dwarfs in the Milky Way halo. We perform a targeted search of HAWC gamma-ray
sources which have no known association with lower-energy counterparts, based
on an unbiased search of the entire sky. With no sources found to strongly
prefer dark matter models, we calculate the ability of HAWC to observe dark
dwarfs. We also compute the HAWC sensitivity to potential future detections for
a given model of dark matter substructure.
