Abstract: | One of the long-standing issues in extra-galactic astronomy is the inability to explain how massive, monster, galaxies assemble and evolve. In the standard theory, massive galaxies are the extreme limit of galaxy evolution having undergone more mergers than less massive galaxies. Brightest Cluster Galaxies (BCGs) are the most massive galaxies observed today, however, their recent assembly is still poorly understood observationally. These extreme galaxies are an important place to examine flaws in models of galaxy evolution, because they push the models to their limits, however without strong observational understanding it is not possible to truly test the models. |
