Dr. Tom Maccarone
Texas Tech University

Abstract

In the past few years, a series of discoveries have been made of objects which appear to be accreting stellar mass black holes in globular clusters -- both in the Milky Way and in other nearby galaxies. I will discuss why the theoretical work which suggested that such objects would be unlikely to exist, the observations showing they do exist, some of the unusual aspects of some of the individual sources, and the new theoretical framework for producing them.

Abstract

Among the different effects of secular evolution of galaxies we find how bars influence enormously their host galaxies. For many years now, it is known how the evolution of bars will produce different boxy/peanut and X-shape bulges. In this context our Milky Way is an example of a boxy bulge, and we will present a self consistent N-body simulation of a barred galaxy that will be compared with some of the Milky Way available data. We will compare the model in terms of morphology and structure, kinematics and finally metallicity gradients.
