Indications of disequilibrium throughout the Milky Way (MW) highlight the need for compact, flexible, non-parametric descriptions of phase–space distributions of galaxies. We present a new representation of the current dark matter (DM) distribution and potential derived from N-body simulations of the MW and Large Magellanic Cloud (LMC) system using basis function expansions (BFEs). We incorporate methods to maximize the physical signal in the representation. As a result, the simulations of 108… 
All-sky dynamical response of the Galactic halo to the Large Magellanic Cloud.
The detection of both the local wake and northern overdensity in a map of the Galaxy based on 1,301 stars at Galactocentric distances between 60 and 100 kiloparsecs demonstrate that the outer halo is not in dynamical equilibrium, as is often assumed.
A holistic review of a galactic interaction
Our situation as occupants of the Milky Way (MW) Galaxy, bombarded by the Sagittarius dwarf galaxy, provides an intimate view of physical processes that can lead to the dynamical heating of a
Measuring the Sun's velocity using Gaia EDR3 observations of Stellar Streams
We measure the Sun's velocity with respect to the Galactic halo using Gaia Early Data Release 3 (EDR3) observations of stellar streams. Our method relies on the fact that, in low-mass streams, the
Gaia Early Data Release 3. Acceleration of the solar system from Gaia astrometry
Context. Gaia Early Data Release 3 (Gaia EDR3) provides accurate astrometry for about 1.6 million compact (QSO-like) extragalactic sources, 1.2 million of which have the best-quality five-parameter
Machine-learned dark matter subhalo candidates in the 4FGL-DR2: search for the perturber of the GD-1 stream
The detection of dark matter subhalos without a stellar component in the Galactic halo remains a challenge. We use supervised machine learning to identify high-latitude gamma-ray sources with dark

Over the past several decades, unexpected astronomical discoveries have been fueling a new wave of particle model building and are inspiring the next generation of ever-more-sophisticated simulations
The Extended Tidal Tails of NGC 7089 (M2)
Using photometry and proper motions from Gaia Early Data Release 3, we detect a 45° long trailing stellar debris stream associated with the old, metal-poor globular cluster NGC 7089. With a width on
The Global Dynamical Atlas of the Milky Way Mergers: Constraints from Gaia EDR3–based Orbits of Globular Clusters, Stellar Streams, and Satellite Galaxies
The Milky Way halo was predominantly formed by the merging of numerous progenitor galaxies. However, our knowledge of this process is still incomplete, especially in regard to the total number of
The Local Group Mass in the Light of Gaia
High-accuracy proper motions (PMs) of M31 and other Local Group (LG) satellites have now been provided by the Gaia satellite. We revisit the timing argument to compute the total mass M of the LG from
Radialization of Satellite Orbits in Galaxy Mergers
We consider the orbital evolution of satellites in galaxy mergers, focusing on the evolution of eccentricity. Using a large suite of N-body simulations, we study the phenomenon of satellite orbital


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 of
Models of distorted and evolving dark matter haloes
We investigate the ability of basis function expansions to reproduce the evolution of a Milky Way-like dark matter halo, extracted from a cosmological zoom-in simulation. For each snapshot, the
Limit on the LMC mass from a census of its satellites
We study the orbits of dwarf galaxies in the combined presence of the Milky Way and Large Magellanic Cloud (LMC) and find six dwarfs that were likely accreted with the LMC (Car 2, Car 3, Hor 1, Hyi
DM halo morphological types of MW-like galaxies in the TNG50 simulation: Simple, Twisted, or Stretched
We present a comprehensive study of the shape analysis of dark matter (DM) halos in a sample of 25 Milky Way (MW) like galaxies in the TNG50 run of the IllustrisTNG project. Using an Enclosed Volume
Deflection of the hypervelocity stars by the dance of the Milky Way and Large Magellanic Cloud
Stars slingshotted by the supermassive black hole at the Galactic centre will escape the Milky Way so quickly that their trajectories will be almost straight lines. Previous works have shown how

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
Evidence from the H3 Survey That the Stellar Halo Is Entirely Comprised of Substructure
In the $\Lambda$CDM paradigm the Galactic stellar halo is predicted to harbor the accreted debris of smaller systems. To identify these systems, the H3 Spectroscopic Survey, combined with $Gaia$, is
Piercing the Milky Way: an all-sky view of the Orphan Stream
We use astrometry, broad-band photometry, and variability information from the Data Release 2 of ESA’s Gaia mission (GDR2) to identify members of the Orphan Stream (OS) across the whole sky. The
