Accurate calculations of the WIMP halo around the Sun and prospects for gamma ray detection

Understand

Weakly interacting massive particles (WIMPs) can be captured by heavenly objects, like the Sun.

• Under the process of being captured by the Sun, they will build up a population of WIMPs around it, that will eventually sink to the core of the Sun.
• It has been argued with simpler estimates before that this halo of WIMPs around the Sun could be a strong enough gamma ray source to be a detectable signature for WIMP dark matter.
• We here revisit the problem using detailed Monte Carlo simulations and detailed composition and structure information about the Sun to estimate the size of the gamma ray flux.
