 | Gondolo, Paolo | Annual modulation of dark matter in the presence of streams | In addition to a smooth component of weakly interacting massive particle (WIMP) dark matter in galaxies, there may be streams of material; the effects of WIMP streams on direct detection experiments is examined in this paper. The contribution to the count rate due to the stream cuts off at some char... | WIMP streams; Weakly interacting massive particles; Cutoff energy; Halo models; Sagittarius dwarf galaxy; Recoil energy; Sgr stream | 2006-08 |

 | Gondolo, Paolo | Effect of a late decaying scalar on the neutralino relic density | If the energy density of the Universe before nucleosynthesis is dominated by a scalar field Ø that decays and reheats the plasma to a temperature TRH smaller than the standard neutralino freeze-out temperature, the neutralino relic density differs from its standard value. In this case, the relic de... | Neutralinos; Relic density; Reheating temperature | 2006-10 |

 | Gondolo, Paolo | Neutralino with the right cold dark matter abundance in (almost) any supersymmetric model | We consider nonstandard cosmological models in which the late decay of a scalar field Ø reheats the Universe to a low reheating temperature, between 5 MeV and the standard freeze-out temperature of neutralinos of mass mx. We point out that in these models all neutralinos with standard density Ώstd... | Neutralinos; Reheating temperature | 2006-07 |

 | Gondolo, Paolo | Phase-space distribution of unbound dark matter near the sun | We resolve discrepancies in previous analyses of the flow of collisionless dark matter particles in the Sun's gravitational field. We determine the phase-space distribution of the flow both numerically, tracing particle trajectories back in time, and analytically, providing a simple correct relati... | Phase-space distribution; Gravitational field; Velocity functions | 2006-10 |

 | Gondolo, Paolo | Stellar orbit constraints on neutralino annihilation at the galactic center | Dark matter annihilation has been proposed to explain the TeV gamma rays observed from the Galactic Center. We study constraints on this hypothesis coming from the mass profile around the Galactic Center measured by observing stellar dynamics. We show that for several proposed WIMP candidates, the... | Neutralinos; Annihilation | 2006-09 |
