Radio Signal by Galactic Dark Matter (2008)
Borriello, Enrico, Cuoco, Alessandro, Miele, Gennaro
An interesting strategy for indirect detection of Dark Matter comes through the amounts of electrons and positrons usually emitted by DM pair annihilation. The e+e- gyrating in the galactic magnetic...
Radio constraints on dark matter annihilation in the galactic halo and its substructures (2008)
Borriello, Enrico, Cuoco, Alessandro, Miele, Gennaro
Annihilation of Dark Matter usually produces together with gamma rays comparable amounts of electrons and positrons. The e+e- gyrating in the galactic magnetic field then produce secondary...
Ultra-high energy Neutrinos from Centaurus A and the Auger hot spot (2007)
Cuoco, Alessandro, Hannestad, Steen
The Pierre Auger collaboration has reported a correlation between Ultra-High Energy Cosmic Rays (UHECR) and nearby Active Galactic Nuclei (AGNs) within 75 Mpc. Two of these events fall within 3...
Angular Signatures of Annihilating Dark Matter in the Cosmic Gamma-Ray Background (2007)
Cuoco, Alessandro, Brandbyge, Jacob, Hannestad, Steen, Haugboelle, Troels, Miele, Gennaro
The extragalactic cosmic gamma-ray background (CGB) is an interesting channel to look for signatures of dark matter annihilation. In particular, besides the imprint in the energy spectrum, peculiar...
Cuoco, Alessandro, Hannestad, Steen, Haugboelle, Troels, Kachelriess, Michael, Serpico, Pasquale D.
The arrival directions of ultrahigh energy cosmic rays (UHECRs) may show anisotropies on all scales, from just above the experimental angular resolution up to medium scales and dipole anisotropies....
