ΛCDM Formation Models<br />
• predictions:<br />
– Hierarchical formation: small structures<br />
collapse first (youngest / massive galaxies<br />
form in clusters today)<br />
– Galaxies evolve inside-out<br />
– “Universal” (NFW) halo profiles<br />
– Sub-maximal disks: DM dominates at all radii<br />
(for R > 1 disk scale length)<br />
mass distribution on all scales is an<br />
important constraint of cosmological models
