A Universal Distribution of Dark Matter in Milky Way-like galaxies and How to Infer It

Sam Cheng-Tse Huang, Matthew R. Buckley, Justin I. Read +1

The authors identify a near‑universal dark‑matter phase‑space distribution in Milky Way‑mass galaxy simulations, show it can be inferred from metal‑poor stellar data, and construct…

EDGE-INFERNO: How chemical enrichment assumptions impact the individual stars of a simulated ultra-faint dwarf galaxy

Eric P. Andersson, Martin P. Rey, Robert M. Yates +6

The chemical abundances of stars in galaxies are a fossil record of the star formation and stellar evolution processes that regulate galaxy formation, including the stellar initial…

The PARADIGM project II: The lifetimes and quenching of satellites in Milky Way-mass haloes

Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz +2

The abundance and star-formation histories of satellites of Milky Way (MW)-like galaxies are linked to their hosts' assembly histories. To explore this connection, we use the PARAD…

The radial acceleration relation at the EDGE of galaxy formation: testing its universality in low-mass dwarf galaxies

Mariana P. Júlio, Justin I. Read, Marcel S. Pawlowski +6

A tight correlation between the baryonic and observed acceleration of galaxies has been reported over a wide range of mass () - the Radi…

The emergence of globular clusters and globular-cluster-like dwarfs

Ethan D. Taylor, Justin I. Read, Matthew D. A. Orkney +7

Globular clusters (GCs) are among the oldest and densest stellar systems in the Universe, yet how they form remains a mystery. Here we present a suite of cosmological simulations i…

Trial by FIRE: Probing the dark matter density profile of dwarf galaxies with GraphNPE

Tri Nguyen, Justin Read, Lina Necib +4

The Dark Matter (DM) distribution in dwarf galaxies provides crucial insights into both structure formation and the particle nature of DM. GraphNPE (Graph Neural Posterior Estimato…
