Environmental Impacts on Simulated Galaxy Properties
… in the IllustrisTNG simulations, I show how the splashback radius, which defines a halo’s boundary by separating orbiting material from infalling material, varies depending on the measurement method. I then show how selection effects can bias measurements of the splashback radius by examining …

The structure and evolution of dark matter halos and their implications for cosmology
… history and environment. I study how the splashback feature, which is a steepening of the slope of the density profile in a narrow, localized region near the outskirts of the halo, is in reality a powerful physical length scale within the halo that naturally demarcates the actual boundary …

Extracting information from the exteriors of dark matter halos
… exteriors of clusters is indeed related to the splashback radius. In addition, we investigate the possibility of observing matter that has been stripped by tidal interactions as galaxies enter clusters. We find that we can indeed detect tidal tails when using full 3D data but cannot do so when …
