Description
Dwarf Spheroidal (dSphs) galaxies are suspected dark matter dense sources within our galactic neighborhood. They are otherwise quiet locations that are low of other high energy gamma-ray sources which makes them ideal dark matter targets. HAWC's previous dark matter search toward dSph was performed with older reconstruction techniques and significantly less data. This iteration leverages HAWC's improved energy estimation methods and sensitivity at high zenith angles. We also incorporate improved particle physics models and ultra-faint dwarves. This study is over a heavy dark matter regime not well explored ranging from 1 TeV to 10 PeV in dark matter mass. In the case of a null result, we set limits on the velocity-weighted cross section.
