  1. All-Sky Kinematics of the Distant Halo: The Reflex Response to the LMC

    Publication
    The infall of the Large Magellanic Cloud (LMC) is predicted to displace the inner Milky Way (MW), imprinting an apparent 'reflex motion' on the observed velocities of distant …

  2. On the Hunt for the Origins of the Orphan--Chenab Stream: Detailed Element Abundances with APOGEE and Gaia

    Publication
    Stellar streams in the Galactic halo are useful probes of the assembly of galaxies like the Milky Way. Many tidal stellar streams that have been found in recent …

  3. Snails across Scales: Local and Global Phase-mixing Structures as Probes of the Past and Future Milky Way

    Publication
    Signatures of vertical disequilibrium have been observed across the Milky Way's (MW's) disk. These signatures manifest locally as unmixed phase spirals in z–vz space ("snails …

  4. Weighing the Galactic disk using phase-space spirals

    Publication
    In this fourth article on weighing the Galactic disk using the shape of the phase-space spiral, we have tested our method on a billion particle three-dimensional …

  5. Migration and Mixing in the Galactic Disc from Encounters between Sagittarius and the Milky Way

    Publication
    Stars born on near-circular orbits in spiral galaxies can subsequently migrate to different orbits due to interactions with non-axisymmetric disturbances within the disc such as bars …

  6. The Clustering of Orbital Poles Induced by the LMC: Hints for the Origin of Planes of Satellites

    Publication
    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 …

  7. Quantifying the Impact of the Large Magellanic Cloud on the Structure of the Milky Way's Dark Matter Halo Using Basis Function Expansions

    Publication
    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 …

  8. Resolving local and global kinematic signatures of satellite mergers with billion particle simulations

    Publication
    In this work, we present two new ∼109 particle self-consistent simulations of the merger of a Sagittarius-like dwarf galaxy with a Milky Way (MW)-like disc …

  9. The Galactic Midplane Is Not a Plane: Implications for Dynamical Analysis with Gaia Data and Beyond

    Publication
    Orbital properties of stars, computed from their six-dimensional phase space measurements and an assumed Galactic potential, are used to understand the structure and evolution of the Galaxy …
