EDGE -- Dark matter or astrophysics? Breaking dark matter heating degeneracies with HI rotation in faint dwarf galaxies

Martin P. Rey, Matthew D. A. Orkney, Justin I. Read +6

Low-mass dwarf galaxies are expected to reside within dark matter haloes that have a pristine, `cuspy' density profile within their stellar half-light radii. This is because they f…

Action-based dynamical models of M31-like galaxies

Paula Gherghinescu, Payel Das, Robert J. J. Grand +1

In this work, we present an action-based dynamical equilibrium model to constrain the phase-space distribution of stars in the stellar halo, present-day dark matter distribution, a…

EDGE: The direct link between mass growth history and the extended stellar haloes of the faintest dwarf galaxies

Alex Goater, Justin I. Read, Noelia E. D. Noël +9

Ultra-faint dwarf galaxies (UFDs) are commonly found in close proximity to the Milky Way and other massive spiral galaxies. As such, their projected stellar ellipticity and extende…

Exploring the diversity and similarity of radially anisotropic Milky Way-like stellar haloes: implications for disrupted dwarf galaxy searches

Matthew D. A. Orkney, Chervin F. P. Laporte, Robert J. J. Grand +7

We investigate the properties of mergers comparable to the Gaia-Sausage-Enceladus (GSE) using cosmological hydrodynamical simulations of Milky Way-like galaxies. The merger progeni…

EDGE: The shape of dark matter haloes in the faintest galaxies

Matthew D. A. Orkney, Ethan Taylor, Justin I. Read +5

Collisionless Dark Matter Only (DMO) structure formation simulations predict that Dark Matter (DM) haloes are prolate in their centres and triaxial towards their outskirts. The add…
