EDGE: dwarf-galaxy scaling relations and the role of feedback

Rey, M. P., Agertz, O., Pontzen, A., et al.

Presents EDGE scaling relations for dwarf galaxies, highlighting ongoing EDGE work on dark matter, feedback and chemical enrichment.

MNRAS, 541, 1195 (2025)

MEGATRON: how the first stars create an iron metallicity plateau in the smallest dwarf galaxies

Rey, M. P., Katz, H., Cadiou, C., Sanati, M., Agertz, O., et al.

Bridges cosmic dawn and the present day, showing how chemical enrichment from the very first (Population III) stars leaves a measurable iron fingerprint in the oldest dwarf galaxies we can still observe.

2024

Boosting galactic outflows with enhanced resolution

Rey, M. P., Katz, H. B., Cameron, A. J., Devriendt, J., Slyz, A.

Shows that better-resolved galactic outflows carry up to five times more mass and energy without changing any astrophysical model, reshaping how we predict the regulation of galaxies over cosmic time.

MNRAS, 528, 5412 (2024)

2023

VINTERGATAN-GM: the cosmological imprints of early mergers on Milky-Way-mass galaxies

Rey, M. P., Agertz, O., Starkenburg, T. K., Renaud, F., Joshi, G. D., et al.

Pioneers an entirely new, controlled approach to Galactic archaeology, causally linking the stars in a Milky-Way-like galaxy's halo to the early mergers that built it.

MNRAS, 521, 995 (2023)

2019

EDGE: the origin of scatter in ultra-faint dwarf stellar masses and surface brightnesses

Rey, M. P., Pontzen, A., Agertz, O., Orkney, M. D. A., Read, J. I., et al.

Pins down how the smallest dwarf galaxies get their stellar mass, explaining the scatter in the masses and sizes of the faintest galaxies.

ApJL, 886, L3 (2019)

2018

Quadratic genetic modifications: a streamlined route to simulations with controlled merger history

Rey, M. P., Pontzen, A.

Establishes the theoretical foundations of “genetic modification”, the method that turns cosmological simulations into controlled experiments and underpins much of my later work.

MNRAS, 474, 45 (2018)
