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 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…

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…

Milky Way satellite velocities reveal the Dark Matter power spectrum at small scales

Ivan Esteban, Annika H. G. Peter, Stacy Y. Kim

Dark Matter (DM) properties at small scales remain uncertain. Recent theoretical and observational advances have provided the tools to narrow them down. Here, we show for the first…

The PAndAS View of the Andromeda Satellite System. IV Global properties

Amandine Doliva-Dolinsky, Nicolas F. Martin, Zhen Yuan +8

We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf galaxies located in th…

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…

Andromeda XXV -- a dwarf galaxy with a low central dark matter density

Emily J. E. Charles, Michelle L. M. Collins, R. Michael Rich +7

Andromeda (And) XXV has previously been reported as a dwarf spheroidal galaxy (dSph) with little-to-no dark matter. However, the uncertainties on this result were significant. In t…

Streams on FIRE: Populations of Detectable Stellar Streams in the Milky Way and FIRE

Nora Shipp, Nondh Panithanpaisal, Lina Necib +18

We present the first detailed study comparing the populations of stellar streams in cosmological simulations to observed Milky Way dwarf galaxy streams. In particular, we compare s…

Snowmass2021 Cosmic Frontier White Paper: Dark Matter Physics from Halo Measurements

Keith Bechtol, Simon Birrer, Francis-Yan Cyr-Racine +41

The non-linear process of cosmic structure formation produces gravitationally bound overdensities of dark matter known as halos. The abundances, density profiles, ellipticities, an…
