"The Ecology of the Galactic Center"

Abstract:

I review the many processes at play in the very centers of galaxies in particular those which may produce the various exotic objects seen in the center of our own Galaxy. I consider how collisions between various different stellar species, star-disk interactions and the assembly history of the galactic center may play a role in explaining the flattened surface density profile of red giants within 0.4 pc or so of the supermassive black hole. Such studies may help us to understand the assembly history of the central cluster and the growth of the supermassive black hole.
