Inverted initial conditions: exploring the growth of cosmic structure and voids
Andrew Pontzen, Anže Slosar, Nina Roth +1
We introduce and explore "paired" cosmological simulations. A pair consists of an A and B simulation with initial conditions related by the inversion $δ_A(x, t_{initial})=-δ_B(x,t_…
Genetically modified halos: towards controlled experiments in CDM galaxy formation
Nina Roth, Andrew Pontzen, Hiranya V. Peiris
We propose a method to generate `genetically-modified' (GM) initial conditions for high-resolution simulations of galaxy formation in a cosmological context. Building on the Hoffma…
Milking the spherical cow: on aspherical dynamics in spherical coordinates
Andrew Pontzen, Justin Read, Romain Teyssier +4
Galaxies and the dark matter halos that host them are not spherically symmetric, yet spherical symmetry is a helpful simplifying approximation for idealised calculations and analys…
