We investigate the population of dwarf galaxies with stellar masses similar to the Large Magellanic Cloud (LMC) and M33 in the EAGLE galaxy formation simulation. In the field, galaxies reside in haloes with stellar-to-halo mass ratios of 1.03+0.50−0.31×10−2 (68 per cent confidence level); systems like the LMC, which have an SMC-mass satellite, reside in haloes about 1.3 times more massive, which suggests an LMC halo mass at infall, M200=3.4+1.8−1.2×1011M⊙ (68 per cent confidence level… Expand
The survival of globular clusters in a cuspy Fornax
It has long been argued that the globular clusters (GCs) in the Fornax dwarf galaxy indicate that its dark matter halo is likely to have a shallow density profile with a core of size ∼1 kpc. WeExpand
Magellanic satellites in ΛCDM cosmological hydrodynamical simulations of the Local Group
We use the APOSTLE ΛCDM cosmological hydrodynamical simulations of the Local Group to study the recent accretion of massive satellites into the halo of Milky Way (MW)-sized galaxies. These systemsExpand
The Dearth of Differences between Central and Satellite Galaxies. II. Comparison of Observations with L-GALAXIES and EAGLE in Star Formation Quenching
As we demonstrated in Paper I, the quenched fractions of central and satellite galaxies as function of halo mass are extremely similar, as long as one controls for stellar mass. The same holds forExpand
Milky Way Satellite Census. II. Galaxy–Halo Connection Constraints Including the Impact of the Large Magellanic Cloud
The population of Milky Way (MW) satellites contains the faintest known galaxies and thus provides essential insight into galaxy formation and dark matter microphysics. Here we combine a model of theExpand
The aftermath of the Great Collision between our Galaxy and the Large Magellanic Cloud
The Milky Way (MW) offers a uniquely detailed view of galactic structure and is often regarded as a prototypical spiral galaxy. But recent observations indicate that the MW is atypical: it has anExpand
Evolution of galactic planes of satellites in the eagle simulation
We study the formation of planes of dwarf galaxies around Milky Way (MW)-mass haloes in the eagle galaxy formation simulation. We focus on satellite systems similar to the one in the MW: spatiallyExpand
The mass of the Milky Way from satellite dynamics
We present and apply a method to infer the mass of the Milky Way (MW) by comparing the dynamics of MW satellites to those of model satellites in the eagle cosmological hydrodynamics simulations. AExpand
Hunting for the Dark Matter Wake Induced by the Large Magellanic Cloud
Satellite galaxies are predicted to generate gravitational density wakes as they orbit within the dark matter (DM) halos of their hosts, causing their orbits to decay over time. The recent infall ofExpand
The milky way total mass profile as inferred from Gaia DR2
We determine the Milky Way (MW) mass profile inferred from fitting physically motivated models to the Gaia DR2 Galactic rotation curve and other data. Using various hydrodynamical simulations ofExpand
Reflex motion in the Milky Way stellar halo resulting from the Large Magellanic Cloud infall
We present the results of N-body models of the Milky Way and Large Magellanic Cloud system and study the kinematic reflex motion in the stellar halo owing to the barycentre displacement of the disc.Expand


Galaxy And Mass Assembly (GAMA) : in search of Milky Way Magellanic Cloud analogues.
Analysing all Galaxy And Mass Assembly (GAMA) galaxies within a factor of 2 (±0.3 dex) of the stellar mass of the Milky Way (MW), there is a 11.9 per cent chance that one of these galaxies will haveExpand
The multiplicity and anisotropy of galactic satellite accretion
We study the incidence of group and filamentary dwarf galaxy accretion into Milky Way (MW) mass haloes using two types of hydrodynamical simulations: EAGLE, which resolves a large cosmologicalExpand
The Hydrangea simulations: galaxy formation in and around massive clusters
We introduce the Hydrangea simulations, a suite of 24 cosmological hydrodynamic zoom-in simulations of massive galaxy clusters (M200c = 1014–1015.4 M⊙) with baryon particle masses of ∼106 M⊙.Expand
Satellites of LMC-mass dwarfs: close friendships ruined by Milky Way mass haloes
Motivated by the recent discovery of several dwarfs near the Large Magellanic Cloud (LMC), we study the accretion of massive satellites onto Milky Way (MW)/M31-like haloes using the ELVIS suite ofExpand
The origin of scatter in the stellar mass–halo mass relation of central galaxies in the EAGLE simulation
We use the hydrodynamical EAGLE simulation to study the magnitude and origin of the scatter in the stellar mass–halo mass relation for central galaxies.We separate cause and effect by correlatingExpand
Satellite abundances around bright isolated galaxies
We study satellite galaxy abundances by counting photometric galaxies from the Eighth Data Release of the Sloan Digital Sky Survey (SDSS/DR8) around isolated bright primary galaxies from SDSS/DR7. WeExpand
The colours of satellite galaxies in the Illustris simulation
Observationally, the fraction of blue satellite galaxies decreases steeply with host halo mass, and their radial distribution around central galaxies is significantly shallower in massive (M* ≥ 1011Expand
How do galaxies populate dark matter haloes
For any assumed standard stellar initial mass function, the Sloan Digital Sky Survey (SDSS) gives a precise determination of the abundance of galaxies as a function of their stellar mass over theExpand
Mergers are a common phenomenon in hierarchical structure formation, especially for massive galaxies and clusters, but their importance for dwarf galaxies in the Local Group remains poorlyExpand
