Dark Matter on the Smallest Scales
This work investigates the dark matters structures that form on the smallest cosmological scales. We find that the types and abundances of structures which form at approximately Earth-mass scales are very sensitive to the nature of dark matter. We explore various candidates for dark matter and determine the corresponding properties of small-scale structure. In particular, we discuss possibiliti...
متن کاملImpact of dark matter microhalos on signatures for direct and indirect detection
Detecting dark matter as it streams through detectors on Earth relies on knowledge of its phase space density on a scale comparable to the size of our Solar System. Numerical simulations predict that our galactic halo contains an enormous hierarchy of substructures, streams and caustics, the remnants of the merging hierarchy that began with tiny Earth-mass microhalos. If these bound or coherent...
متن کاملDark matter with ultra compact mini halos
The isocurvature mode of dark matter is not damped away during kinetic decoupling from the thermal plasma. For weakly interaction massive particle as dark matter, the large density perturbation can generate the small scale ultra compact mini halos and the annihilation of dark matter inside them can give accessible signatures in the indirect detection of dark matter. The early matter domination ...
متن کاملIndirect Searches for Kaluza-klein Dark Matter∗
In this talk, we discuss the potential for the indirect detection of Kaluza-Klein dark matter using neutrino telescopes and cosmic positron experiments. We find that future kilometer-scale neutrino telescopes, such as IceCube, as well as future experiments capable of measuring the cosmic positron spectrum, such as PAMELA and AMS-02, will be quite sensitive to this scenario. Current data from th...
متن کاملIndirect Search for Neutralino Dark Matter with High Energy Neutrinos
We investigate the prospects of indirect searches for supersymmetric neutralino dark matter. Relic neutralinos gravitationally accumulate in the Sun and their annihilations produce high energy neutrinos. Muon neutrinos of this origin can be seen in large detectors like AMANDA, IceCube and ANTARES. We evaluate the relic density and the detection rate in several models — the minimal supersymmetri...
