"The concept of the cosmic web, viewing the Universe as a set of discrete galaxies held together by gravity, is deeply engrained in cosmology. Yet, little is known about the most effective construction and the characteristics of the underlying network," they explain in a paper about their research, published at arXiv.org.
The scientists compared their models to the actual Universe, to find which definition of the cosmic web offers the best correlations between the physical characteristics of the connected galaxies.

They found the "nearest neighbors model" (M3) in which the length of each link depends on the distance to the nearest galaxy, to be the most accurate algorithm.
An interface of each model is available on their Cosmic Web website, which allows users to switch the type of connections that bind galaxies together and rotate, zoom and filter the models.
