EDGE: The emergence of dwarf galaxy scaling relations from cosmological radiation-hydrodynamics simulations
Martin P. Rey, Ethan Taylor, Emily I. Gray +14
We present a new suite of EDGE (`Engineering Dwarfs at Galaxy formation's Edge') cosmological zoom simulations. The suite includes 15 radiation-hydrodynamical dwarf galaxies coveri…

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…

From particles to orbits: precise dark matter density profiles using dynamical information
Claudia Muni, Andrew Pontzen, Jason L. Sanders +3
We introduce a new method to calculate dark matter halo density profiles from simulations. Each particle is 'smeared' over its orbit to obtain a dynamical profile that is averaged…
