Talk Title |
Gravitational hydrodynamics of large scale structure formation |
|
Abstract |
The gravitational hydrodynamics of the primordial plasma with neutrino hot dark matter is considered as a challenge to the bottom-up CDM paradigm. Viscosity and turbulence induce a top-down fragmentation scenario before and at decoupling. The first step is the creation of voids in the plasma, which expand to $37$ Mpc on the average now. The remaining matter clumps turn into galaxy clusters. Turbulence produced at expanding void boundaries causes a linear morphology of 3 kpc fragmenting protogalaxies along vortex lines. At decoupling galaxies and proto-globular star clusters arise; the latter constitute the galactic dark matter halos and consist themselves of earth-mass H-He planets. These planets are observed in microlensing and in planetary nebulae when heated by a white dwarf. The approach also explains the Tully-Fisher and Faber-Jackson relations, and CMB temperature fluctuations of micro-Kelvins. |
