International simulation collaborations
My work runs through large international team-based projects.
MEGATRON
A simulation programme connecting the first stars, early chemical enrichment and the emission and absorption lines now observed in high-redshift galaxies. As co-PI I help lead a team of 25+ observers and theorists (Chicago and Oxford), using the Ramses-RTZ code to understand how the first chemical elements were produced.
Rey et al. 2025 (arXiv)EDGE
Simulating the faintest dwarf galaxies in the Universe to probe the nature of dark matter and the first galaxies. EDGE is an active international collaboration, producing recent work on dwarf-galaxy scaling relations, the nature of dark matter, feedback-driven outflows, and chemical enrichment in the smallest systems.
edge-simulation.github.ioVINTERGATAN
Simulating the formation of Milky-Way-like galaxies, and the basis of my controlled approach to Galactic archaeology.
vintergatanGM Galaxies
The research programme behind the “genetic modification” technique for running controlled experiments on galaxy formation.
gmgalaxies.orgOpen-source software
Core developer of genetIC, and a regular contributor to pynbody, tangos and the Ramses-RTZ code. My repositories are on GitHub.
Open Journal of Astrophysics
Editor since 2024 for a diamond open-access, community-run journal that is free to read and to publish in. More on open science.
