"Galaxy Mergers in a
In a universe dominated by dark
matter and dark energy, galaxies and their host dark matter halos
grow primarily through mergers with other galaxies. Having an
accurate description of the mergers
of dark matter halos is therefore a key step in understanding galaxy
formation and evolution.
I will give an overview of observational evidence for galaxy mergers
and describe some recent
theoretical efforts in quantifying the rates of mergers and the impact
on the growths of galaxies
and their central supermassive black holes.
