The Evolution of the Distribution of Enriched Material in Large Scale Structure from z=3 to z=0
Abstract
The local cosmic environment influences the formation and evolution of galaxies. This environment is composed of many galaxies, immersed in an intricate web of dark matter, forming extensive clusters and filaments with vast voids between them. A history of this evolution is preserved as a relic in intergalactic medium (IGM) permeating this structure. Using a computer vision algorithm, adapted to identify clusters, filaments and voids, we characterize the large-scale structure and its constituent galaxies in our GADGET-2 simulations. Once these regions of interest are identified, all the constituent gas and dark matter particles forming this structure are traced back in redshift. The selected region of interest is then re-run at higher resolution. With metal cooling and feedback enabled, we follow the evolution of the member galaxies and the enrichment of the structures as a function of redshift.
