Dark Matter and Cold Fractal Clouds
Abstract
Description
There is strong evidence for a large fraction of dark matter in the Universe. Some of the evidence and candidates for dark matter are reviewed. Dark matter in spiral galaxies may be in the form of cold dense clouds of molecular hydrogen. This model is presented in more detail and perspectives for detecting the cold H_2 are discussed.
