Dark Matter Halos and z~2 Galaxies: Mergers, Smooth Accretion, and Feedback

Shy Genel  (CfA), 

I will describe the different growth modes of dark matter halos in the LCDM cosmological model as inferred from large cosmological N-body simulations. That growth is characterized by both mergers and accretion of \"smooth\" material. I will also present observations of rapidly star-forming and turbulent galaxy disks at z~2, and discuss attempts to model such galaxies using high-resolution, \"zoom-in\", cosmological hydrodynamical simulations.
