1 Gondolo, PaoloCosmic ray positron excess and neutralino dark matterUsing a new instrument, the HEAT Collaboration has confirmed the excess of cosmic ray positrons that they first detected in 1994. We explore the possibility that this excess is due to the annihilation of neutralino dark matter in the galactic halo. We confirm that neutralino annihilation can produ...Neutralinos; Supersymmetric models; Positron flux; Annihilations2002-02
2 Gondolo, PaoloDark stars: BegynnelsenThe first phase of stellar evolution in the history of the universe may be Dark Stars, powered by dark matter heating rather than by fusion. Weakly interacting massive particles, which are their own antiparticles, can annihilate and provide an important heat source for the first stars in the univers...Dark stars; WIMP; Weakly interacting massive particles; Annihilations2009
3 Gondolo, PaoloEvidence for "sterile neutrino" dark matter?I show that it may be possible to explain the present evidence for a gamma-ray emission from the galactic halo as due to halo WIMP annihilations. Not only the intensity and spatial pattern of the halo emission can be matched but also the relic density of the candidate WIMP can be in the cosmologica...Sterile neutrino; WIMP; Weakly interacting massive particles; Annihilations; Z boson; Higgs sector1998
4 Gondolo, PaoloIndirect detection of a subdominant density component of cold dark matterWe examine the detectability through indirect means of weakly interacting dark matter candidates that may constitute not all but only a subdominant component of galactic cold dark matter. We show that the possibility of indirect detection of neutralinos from their annihilations in the Earth and Su...WIMP; Weakly interacting massive particles; Annihilations2003-01
5 Gondolo, PaoloIndirect neutralino detection rates in neutrino telescopesNeutralinos annihilating in the center of the Sun or the Earth may give rise to a detectable signal of neutrinos. We derive the indirect detection rates for neutrino telescopes in the minimal supersymmetric extension of the standard model. We show that even after imposing all phenomenological and e...Neutralinos; Neutrino telescopes; Relic density; Annihilations1997-02
6 Gondolo, PaoloSection on prospects for dark matter detection of the white paper on the Status and future of ground-based TeV gamma-ray astronomyThis is a report on the findings of the dark matter science working group for the white paper on the status and future of TeV gamma-ray astronomy. The white paper was commissioned by the American Physical Society, and the full white paper can be found on astro-ph (arXiv:0810.0444). This detailed sec...Annihilations; Dwarf spheroidal2008
