Void Galaxies and Active Galactic Nucleus Activity in ZOBOV-identified TNG300 Voids from z = 3 to z = 0
Abstract
Abstract We study void galaxies in the TNG300 simulation between redshifts z = 3 and z = 0. Cosmic void catalogs were constructed using a watershed-based void-finding algorithm, and we define four populations of field galaxies for our investigation: (1) galaxies that are members of a watershed void, (2) galaxies that are located within a radius r ≤ 0.8 R eff of the center of a void, (3) galaxies interior to spheres centered on void centers that have underdensity contrasts
