Title: | Dark Matter Halos and z~2 Galaxies: Mergers, Smooth Accretion, and Feedback |
Abstract: |
---|
In the LCDM model, both dark matter halos and galaxies form hierarchically by mergers but grow also via direct accretion of "smooth" material. First, I will describe these different growth modes of dark matter halos as inferred from large cosmological N-body simulations. Then I will present observations of rapidly star-forming and turbulent galaxy disks at z~2, and discuss high-resolution, "zoom-in", cosmological hydrodynamical simulations that reproduce many of their properties. |
