TALK ABSTRACT:
--------------
In the process of structure formation, clusters of galaxies merge
to form larger scale clusters. During these events, merger shocks
are formed that accelerate energetic electrons and ions which radiate
nonthermal radio, X-ray, and gamma-ray radiations.
In this talk, I describe work performed in collaboration with
Dr. R. Berrington (U. Wyoming) to model the nonthermal
radiations from merging clusters of galaxies, including a detailed
simulation of the three-dimensional merger process.  Implications of
this process for the production of diffuse background gamma rays,
the structure of cold dark matter profiles in clusters of galaxies, and
the acceleration of ultra-high energy cosmic rays are explored, with
specific application to the Coma cluster of galaxies.
