What May Superclusters Tell us About Galaxy Formation?

  • Avishai Dekel (a1)

Abstract

The structure and dynamical properties of superclusters (SC's) may help us distinguish between various scenarios for galaxy formation. N-body simulations and analytic estimates show that (contrary to a common belief) a nondissipative pancake scenario can explain the observed flattening of SC's. Then, the disk-halo structure of the Local SC (LSC) and its velocity field suggest that galaxies form before SC's and not necessarily as a result of a dissipative gas collapse to SC pancakes. A confrontation of the simulations with the data indicates that the LSC has collapsed along its short axis only after z~l.
