We present multiple ultrahigh resolution cosmological hydrodynamic simulations of M⋆≃
104–6.3 Mȯ dwarf galaxies that form within two M vir= 109.5–10 Mȯ dark matter halo initial …

We use high-resolution simulations of isolated dwarf galaxies to study the physics of dark
matter cusp-core transformations at the edge of galaxy formation: M 200= 107–109 M⊙. We …

We report the discovery of a Milky Way satellite in the constellation of Antlia. The Antlia 2
dwarf galaxy is located behind the Galactic disc at a latitude of b∼ 11° and spans 1.26° …

We use high-resolution cosmological simulations of Milky Way (MW) mass galaxies that
include both baryons and dark matter (DM) to show that baryonic physics (energetic …

We present the completed catalog of ultradiffuse galaxy (UDG) candidates (7070 objects)
from our search of the DR9 Legacy Survey images, including distance and total mass …

High-mass galaxies, with halo masses, reveal a remarkable near-linear relation between
their globular cluster (GC) system mass and their host galaxy halo mass. Extending this …

The accreted component of stellar haloes is composed of the contributions of several
satellites, falling on to their host with their different masses, at different times, on different …

Abstract Cold Dark Matter (CDM) models struggle to match the observations at galactic
scales. The tension can be reduced either by dramatic baryonic feedback effects or by …

Due to their proximity, high dark-matter (DM) content, and apparent absence of non-thermal
processes, Milky Way dwarf spheroidal satellite galaxies (dSphs) are excellent targets for …

We compare the kinematics of M31's satellite galaxies to the mass profiles of the subhaloes
they are expected to inhabit in the Λ cold dark matter (ΛCDM) cosmology. We consider the …
