Is dark matter in spiral galaxies cold gas ? II . Fractal models and star non-formation

In a companion paper (Paper I) we have proposed a new candidate to account for the dark matter around spiral galaxies: cold H2 gas in a fractal structure, supported by rotation, and concomitant with the HI disc. We have shown that this hypothesis is compatible with dynamical and observational constraints about disc galaxies, and explains several… CONTINUE READING
