Scalar Fields as Dark Matter |
|
Abstract |
The Scalar Fields as Dark Matter behaves exactly in the same way as Cold Dark Matter at cosmological scales. Nevertheless, at galactic scales this model predicts flat central density dark matter profiles and less formation of substructure, as observed. In this talk we review this properties, deduce some of them in a very simple way and show numerical simulations of galaxies, where the gas form spiral arms and bars as the real galaxies. We conclude that this model fits well the observations at all scales in a simpler way as the cold dark matter paradigm does. |
