Focusing on a minimal dark matter candidate that only interacts with the SM via gravity in a five-dimensional model we find that a large range of dark matter and Kaluza-Klein graviton masses can lead to the observed relic density. The preferred values of the …

"WebRecent studies suggest that only three of the twelve brightest satellites of the Milky Way (MW) inhabit dark matter halos with maximum circular velocity, Vmax, exceeding ∼30 km/s. This is in apparent contradiction with the ΛCDM simulations of the Aquarius Project, which suggest that MW-sized halos should have at least 8 subhalos with Vmax>30 km/s. The … " - Subhalo finder
