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.
