EDGE: A new approach to suppressing numerical diffusion in adaptive mesh simulations of galaxy formation
Andrew Pontzen, Martin P. Rey, Corentin Cadiou +4
We introduce a new method to mitigate numerical diffusion in adaptive mesh refinement (AMR) simulations of cosmological galaxy formation, and study its impact on a simulated dwarf…
VINTERGATAN I: The origins of chemically, kinematically and structurally distinct discs in a simulated Milky Way-mass galaxy
Oscar Agertz, Florent Renaud, Sofia Feltzing +6
Spectroscopic surveys of the Milky Way's stars have revealed spatial, chemical and kinematical structures that encode its history. In this work, we study their origins using a cosm…
VINTERGATAN III: how to reset the metallicity of the Milky Way
Florent Renaud, Oscar Agertz, Eric P. Andersson +5
Using the cosmological zoom simulation VINTERGATAN, we present a new scenario for the onset of star formation at the metal-poor end of the low-[/Fe] sequence in a Milky Way-like…
VINTERGATAN II: the history of the Milky Way told by its mergers
Florent Renaud, Oscar Agertz, Justin I. Read +5
Using the VINTERGATAN cosmological zoom simulation, we explore the contributions of the in situ and accreted material, and the effect of galaxy interactions and mergers in the asse…
GenetIC -- a new initial conditions generator to support genetically modified zoom simulations
Stephen Stopyra, Andrew Pontzen, Hiranya Peiris +2
We present genetIC, a new code for generating initial conditions for cosmological N-body simulations. The code allows precise, user-specified alterations to be made to arbitrary re…
EDGE: From quiescent to gas-rich to star-forming low-mass dwarf galaxies
Martin P. Rey, Andrew Pontzen, Oscar Agertz +3
We study how star formation is regulated in low-mass field dwarf galaxies (), using cosmological high-resolution ($3 \, \text{pc}…
