TITLE High Energy Astrophysics: Indirect Detection of Dark Matter and Propagation of Ultra-High Energy Heavy Nuclei
ABSTRACT We discuss the prospects of indirect detection of Dark Matter through its annihilation radiation in the Galactic halo, under the assumption that it is made of weakly interactive massive particles (WIMPs) and focusing in particular on specific candidates such as the supersymmetric neutralino, the lightest Kaluza-Klein particle in scenarios with unified extra-dimensions, and on generic super-heavy candidates.
We consider three channels of the annihilation flux from the Galactic center: synchrotron radiation, gamma-ray and neutrino flux. Using the present observations we are able to put constraints on the physical parameters of Dark Matter particles and distribution, while the expected sensitivity of future experiments allows us to discuss the prospects of observing Dark Matter candidates in the near future. We also study the possibility of using stellar structure arguments and helioseismic observations to constrain the properties of \DM particles.
In the second part we discuss the propagation of ultra-high energy heavy nuclei in an extra-galactic magnetic field, keeping into account all relevant energy losses. We then study numerically such process and use the results of simulations to analyze different models for the origin of ultra-high energy cosmic rays recently appeared in literature.
