The lensing data of the galaxy cluster Abell 1689 can be explained by an isothermal fermion model with a mass of 1-2 eV. The best candidate is the 1.5 eV neutrino; its mass will be searched down to 0.2 eV in KATRIN 2015. If its righthanded (sterile) modes were created too, there is 20% neutrino hot dark matter. Their condensation on clusters explains the reionization of the intercluster gas without Pop. III stars. Baryonic structure formation is achieved by gravitional hydrodynamics alone… Expand

Why the dark matter of galaxies is clumps of micro-brown-dwarfs and not Cold Dark Matter
Observations of quasar microlensing by Schild 1996 show the baryonic dark matter BDM of galaxies is micro-brown-dwarfs, primordial hydrogen-helium planets formed at the plasma to gas transition 10^13Expand
Gravity at Relativistic Velocities and Dark Matter
The importance of the gravitational attraction between fast neutrinos with inertial and gravitational masses in the Planck mass range may not be limited to the formation of hadrons. The myriads ofExpand
Gravitational hydrodynamics vs observations of voids, Jeans clusters and MACHO dark matter
Gravitational hydrodynamics acknowledges that hydrodynamics is essentially nonlinear and viscous. In the plasma, at $z=5100$, the viscous length enters the horizon and causes fragmentation intoExpand
Gravity, Special Relativity, and the Strong Force: A Bohr-Einstein-de Broglie Model for the Formation of Hadrons
This book shows that the strong interaction forces, which keep hadrons and nuclei together, are relativistic gravitational forces exerted between very small particles in the mass range of neutrinos.Expand
The Evolution of the Hubble Sequence: morpho-kinematics of distant galaxies
The main objective of my thesis was to provide us, for the first time, with a reliable view of the distant Hubble sequence, and its evolution over the past 6 Gyr. To achieve this goal, we haveExpand
