The frequency of dwarf galaxy multiples at low redshift in SDSS versus cosmological expectations
We quantify the frequency of companions of low-redshift (0.013 55 arcsec, projected separations r_p 1:4) steadily increases with decreasing Primary stellar mass, whereas the cosmological “Major
The Missing Satellites of the Magellanic Clouds? Gaia Proper Motions of the Recently Discovered Ultra-faint Galaxies
According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent discovery of ultra-faint dwarf galaxy
The VMC Survey – XL. Three-dimensional structure of the Small Magellanic Cloud as derived from red clump stars
Galaxy interactions distort the distribution of baryonic matter and can affect star formation. The nearby Magellanic Clouds are a prime example of an ongoing galaxy interaction process. Here we use

The Triangulum Extended (TREX) Survey: The Stellar Disk Dynamics of M33 as a Function of Stellar Age
Triangulum (M33) is a low-mass, relatively undisturbed spiral galaxy that offers a new regime in which to test models of dynamical heating. In spite of its proximity, M33's dynamical heating history
The Orbital Histories of Magellanic Satellites Using Gaia DR2 Proper Motions
With the release of Gaia DR2, it is now possible to measure the proper motions (PMs) of the lowest mass, ultra-faint satellite galaxies in the Milky Way's (MW) halo for the first time. Many of these
The Clustering of Orbital Poles Induced by the LMC: Hints for the Origin of Planes of Satellites
A significant fraction of Milky Way (MW) satellites exhibit phase-space properties consistent with a coherent orbital plane. Using tailored N-body simulations of a spherical MW halo that recently
Comparing hypervelocity star populations from the Large Magellanic Cloud and the Milky Way
We predict and compare the distributions and properties of hypervelocity stars (HVSs) ejected from the centres of the Milky Way (MW) and the Large Magellanic Cloud (LMC). In our model, HVSs are
