Cosmology in One Dimension: The Two Component Universe
  We investigate structure formation in a one dimensional model of a
matter-dominated universe using a quasi-newtonian formulation. In addition to
dark matter, luminous matter is introduced to examine the potential bias in the
distributions. We use multifractal analysis techniques to identify structures,
including clusters and voids. Both dark matter and luminous matter exhibit
fractal geometry as the universe evolves over a finite range. We present the
results for the generalized dimensions computed on various scales for each
matter distribution. We compare and contrast the fractal dimensions of two
types of matter for the first time and show how dynamical considerations cause
them to differ.
