We study the formation and evolution of cosmic web, using high-resolution CosmoGrid \$\Lambda\$CDM simulation. In particular, we investigate large-scale structure around void halo groups, compare this to observations VGS-31 galaxy group, which consists three interacting galaxies inside a large void. The such haloes shows great deal tenuous structure, with most systems being embedded in intra-void filaments walls. use Nexus+ algorithm detect walls CosmoGrid, find them be present detectable at every scale. regions embed walls, turn filaments. hypothesize that group formed an environment.
