Wikipedia describes the distribution of Dark Matter as a halo around our galaxy. Are there any laws or equations on the distribution of dark matter?
From what I have read, dark matter does not clump into stars, since it cannot radiate energy. It cannot be seen or directly observed. Does it repel itself? Does baryonic matter concentrate dark matter? Is its shape and distribution fixed relative to itself? Why would it distribute itself on the peripheries of our galaxy? It did not distribute itself to uphold Newton's Law of Universal Gravitation, yet it seems that it is used as such in arguments in some articles and books which I have read on the structures of galaxies.
For our galaxy, is MOND a simpler explanation? Can there be two models? (Similar to, light is both a particle and a wave.)
According to the LCDM Model, which most physicists support, an existing structure of dark matter was needed at our 380,000 year-old universe to accelerate the formation of large structures and galaxies. We know that dark matter must exist to explain the large scale structures in our universe.
