Impact of Dark Matter Velocity Distributions on Capture Rates in the Sun

Understand

Dark matter could be captured in the Sun and self-annihilate, giving rise to an observable neutrino flux.

• Indirect searches for dark matter looking for this signal with neutrino telescopes have resulted in tight constraints on the interaction cross-section of dark matter with ordinary matter.
• We investigate how robust limits are against astro-physical uncertainties.
• We study the effect of the velocity distribution of dark matter in our Galaxy on capture rates in the Sun.
