One Halo, Two Boundaries: Relating Accretion Shocks and Splashback Radii in Galaxy Clusters
Siddhant Sen, Susmita Adhikari, Daisuke Nagai +1
The boundaries of dark matter and gas in clusters are delineated by the splashback radius and the accretion shock, respectively. Theoretically, both of these boundaries are expecte…
Distinguishing Orbiting and Infalling Dark Matter Particles with Machine Learning
Ze'ev Vladimir, Calvin Osinga, Benedikt Diemer +2
Dark matter halos are typically defined as spheres that enclose some overdensity, but these sharp, somewhat arbitrary boundaries introduce non-physical artifacts such as backsplash…
ULULA: An ultra-lightweight 2D hydrodynamics code for teaching and experimentation
Benedikt Diemer
Hydrodynamics is a difficult subject to teach in the classroom because most relevant problems must be solved numerically rather than analytically. While there are numerous public h…
Lost in the FoG: Pitfalls of Models for Large-Scale Hydrogen Distributions
Calvin Osinga, Benedikt Diemer, Francisco Villaescusa-Navarro
Large-scale HI surveys and their cross-correlations with galaxy distributions have immense potential as cosmological probes. Interpreting these measurements requires theoretical mo…
