The Impact of Star Formation and Feedback Recipes on the Stellar Mass and Interstellar Medium of High-Redshift Galaxies

Harley Katz, Martin P. Rey, Corentin Cadiou +2

We introduce MEGATRON, a new galaxy formation model for cosmological radiation hydrodynamics simulations of high-redshift galaxies. The model accounts for the non-equilibrium chemi…

EDGE-INFERNO: Simulating every observable star in faint dwarf galaxies and their consequences for resolved-star photometric surveys

Eric P. Andersson, Martin P. Rey, Andrew Pontzen +4

Interpretation of data from faint dwarf galaxies is made challenging by observations limited to only the brightest stars. We present a major improvement to tackle this challenge by…

EDGE: Predictable Scatter in the Stellar Mass--Halo Mass Relation of Dwarf Galaxies

Stacy Y. Kim, Justin I. Read, Martin P. Rey +6

The stellar-mass--halo-mass (SMHM) relation is central to our understanding of galaxy formation and the nature of dark matter. However, its normalisation, slope, and scatter are hi…

EDGE: Dark matter core creation depends on the timing of star formation

Claudia Muni, Andrew Pontzen, Justin I. Read +5

We study feedback-driven cold dark matter core creation in the EDGE suite of radiation-hydrodynamical dwarf galaxy simulations. Understanding this process is crucial when using obs…

The PARADIGM project I: How early merger histories shape the present-day sizes of Milky-Way-mass galaxies

Gandhali D. Joshi, Andrew Pontzen, Oscar Agertz +3

How mergers affect galaxy formation depends on both feedback processes, and on the geometry and strength of the mergers themselves. We introduce the PARADIGM project, where we stud…

EDGE: A new model for Nuclear Star Cluster formation in dwarf galaxies

Emily I. Gray, Justin I. Read, Ethan Taylor +8

Nuclear Star Clusters (NSCs) are amongst the densest stellar systems in the Universe and are found at the centres of many bright spiral and elliptical galaxies, and up to 4…

The origin of the H line profiles in simulated disc galaxies

Timmy Ejdetjärn, Oscar Agertz, Göran Östlin +2

Observations of ionised H gas in high-redshift disc galaxies have ubiquitously found significant line broadening, km s. To understand whether this…
