How do galaxies populate Dark Matter halos?

For any assumed standard stellar Initial Mass Function, the Sloan Digital Sky Survey (SDSS) gives a precise determination of the abundance of galaxies as a function of their stellar mass over the full stellar mass range 108M⊙ < M∗ < 10 12M⊙. Within the concordance ΛCDM cosmology, the Millennium simulations give precise halo abundances as a function of mass and redshift for all halos within whic...

Scientists May Finally Have "Seen" Dark Matter

There is an asymmetry between the mass of the electric charges, for example proton and electron, can understood by the asymmetrical Planck Distribution Law. This temperature dependent energy distribution is asymmetric around the maximum intensity, where the annihilation of matter and antimatter is a high probability event. The asymmetric sides are creating different frequencies of electromagnet...

How do people know?

To fully understand processes of knowing and knowledge acquisition, it is necessary to examine people's understanding of their own knowing. Individual and developmental differences in what it means to know something, and hence in the criteria for justifying knowledge claims, have potentially wide-ranging implications. In providing support for a claim, young children have difficulty differentiat...
