April 11, 2007 - The Hierarchical Formation of the Milky Way - Dr. Julio Navarro, UVic, Department of Astronomy

NGC5139 - Omega CentauriThe Cold Dark Matter paradigm of structure formation has proved remarkably successful at accounting for the large-sale properties of the Universe, as measured by the clustering and motions of galaxies, as well as by the detailed structure of the temperature fluctuations in the Cosmic Microwave Background. Some of its "natural" predictions regarding the hierarchical assembly of galaxy systems, however, appear at odds with observational data on the dynamics of individual galaxies and of the Milky Way.

I will re-evaluate the constraints that stellar dynamical data in the solar neighbourhood place on the Milky Way's formation history, and I will argue that, contrary to standard wisdom, the accretion and tidal disruption events that characterize hierarchical galaxy formation have played an important role in the formation of the Milky Way. Particularly interesting relicts of these events are the most massive globular cluster in the Galaxy, Omega Centauri, and by the third-brightest star of the northern night-sky, Arcturus.

Julio Navarro is a professor in the Department of Physics and Astronomy at the University of Victoria. He obtained his B.Sc. from Universidad Nacional de C�rdoba, Argentina 1986 and received his Ph.D in 1990 from Universidad Nacional de C�rdoba, Argentina.
