abstract

This contribution is the affirmative side of a debate held with Dr. L. Pietronero at Princeton in June, 1996. I present the observational evidence that the fractal behavior which characterizes the small scale galaxy distribution does not continue to arbitarily large scale, but has a well defined cutoff with an outer length scale of order 30h$^{-1}$ Mpc. For example, plots of the IRAS 1.2 Jy survey exhibit a very clear approach to homogeneity on large scale, in complete contradiction to the endless fractal model.

Discussion (0). Continue with ORCID to comment.

    A review arguing that the galaxy distribution's fractal dimension is best measured with the structure function, and that the canonical correlation length understates the clustering scale.

    astro-ph.CO 2025-09 accept novelty 2.0 of 10

    A review arguing that correlation functions alone cannot capture the cosmic web's structure, and that the structure function and 2D/3D comparisons are needed.
