Hierarchical Galaxy formation in the Local Universe
Hierarchical Galaxy formation in the Local Universe Hierarchical Galaxy formation in the Local Universe
• Stellar Tidal Stream: (edgeon galaxies) • What is the role of these processes in the formation of the halos and their globular cluster systems? • Extended outer disks: • Is observed halo substructure degree consistent with the CMD theory simulations? Where are the “missing satellites”? • Can tidal debris explain the metalrich halos? Can we trace the dark matter around neaby spirals with tidal streams? (faceon galaxies) • Are extended disk of spirals formed via satellite acretion? • What are the mechanisms of star formation in these very low density galactic regions? Are they older than the normal disks?
Tidal streams “Extended disks” Nearby massive spiral galaxies provide an external view of these merger events observed in the Milky Way M104 M83 M31 M94
