How to quench a galaxy
Andrew Pontzen, Michael Tremmel, Nina Roth +5
We show how the interplay between active galactic nuclei (AGN) and merger history determines whether a galaxy quenches star formation at high redshift. We first simulate, in a full…
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…
