In this work, we examine the different properties of galactic satellites in hydrodynamical and pure dark matter simulations. We use three pairs of simulations (collisional and collisionless) starting from identical initial conditions. We concentrate our analysis on pairs of satellites in the hydro and N-body runs that form from the same Lagrangian region. We look at the radial positions, mass-loss as a function of time and orbital parameters of these ‘twin’ satellites. We confirm an overall… Expand
The Distribution of Satellites Around Central Galaxies in a Cosmological Hydrodynamical Simulation
Observations have shown that the spatial distribution of satellite galaxies is not random, but rather is aligned with the major axes of central galaxies (CGs). The strength of the alignment isExpand
ZOMG - III. The effect of halo assembly on the satellite population
We use zoom hydrodynamical simulations to investigate the properties of satellites within galaxy-sized dark-matter haloes with different assembly histories. We consider two classes of haloes atExpand
The spatial distribution of galactic satellites in the Λ cold dark matter cosmology
We investigate the spatial distribution of galactic satellites in high-resolution simulations of structure formation in the Λ cold dark matter (ΛCDM) model: the Aquarius dark matter simulations ofExpand
On the relevance of chaos for halo stars in the solar neighbourhood
In a previous paper based on dark matter only simulations we show that, in the approximation of an analytic and static potential describing the strongly triaxial and cuspy shape of Milky Way-sizedExpand
Streams in the Aquarius stellar haloes
We use the very high resolution, fully cosmological simulations from the Aquarius Project, coupled to a semi-analytical model of galaxy formation, to study the phase-space distribution of halo starsExpand
On the stark difference in satellite distributions around the Milky Way and Andromeda
We compare spherically-averaged radial number counts of bright (> 10^5 Lsun) dwarf satellite galaxies within 400 kpc of the Milky Way (MW) and M31 and find that the MW satellites are much moreExpand
The temperature of hot gas in galaxies and clusters: Baryons dancing to the tune of dark matter
The temperature profile of hot gas in galaxies and galaxy clusters is largely determined by the depth of the total gravitational potential and thereby by the dark matter (DM) distribution. We useExpand
Satellite survival in highly resolved Milky Way class haloes
Surprisingly little is known about the origin and evolution of the Milky Way’s satellite galaxy companions. UV photoionisation, supernova feedback and interactions with the larger host halo are allExpand
We use some of the highest resolution cosmological simulations ever produced of Milky Way-mass galaxies that include both baryons and dark matter to show that baryonic physics (energetic feedbackExpand
The Role of Baryons in Creating Statistically Significant Planes of Satellites around Milky Way-Mass Galaxies
We investigate whether the inclusion of baryonic physics influences the formation of thin, coherently rotating planes of satellites such as those seen around the Milky Way and Andromeda. For fourExpand


Radial distribution and strong lensing statistics of satellite galaxies and substructure using high‐resolution ΛCDM hydrodynamical simulations
We analyse the number density and radial distribution of substructures and satellite galaxies using cosmological simulations that follow the gas dynamics of a baryonic component, including shockExpand
Sinking satellites and the heating of galaxy discs
We have carried out a set of self-consistent N-body simulations to study the interaction between disc galaxies and merging satellites with the aim of determining the disc kinematical changes inducedExpand

Constrained simulations of the Local Group: on the radial distribution of substructures

Response of Dark Matter Halos to Condensation of Baryons: Cosmological Simulations and Improved Adiabatic Contraction Model
The cooling of gas in the centers of dark matter halos is expected to lead to a more concentrated dark matter distribution. The response of dark matter to the condensation of baryons is usuallyExpand

Galactic disks, infall, and the global value of Omega
Stringent limits on the current rate of infall of satellite systems onto spiral galaxies are set on the basis of the thinness and coldness of Galactic disks. For infalling satellites on isotropicallyExpand
