  1. Tracing Red Giant Members of the Globular Cluster Palomar 5 with APOGEE and Gaia

    Publication
    The globular cluster Palomar 5 (Pal 5) is in the process of being tidally shredded as it orbits the Milky Way. Its core is currently at a heliocentric …

  2. The Star Formation History and Evolution of the Ultra-Diffuse M81 Satellite, F8D1

    Publication
    We present deep HST imaging of one of the nearest ultra-diffuse galaxies (UDGs) outside of the Local Group: F8D1, a satellite of M81 known to be tidally …

  3. Prospects for Detecting Gaps in Globular Cluster Stellar Streams in External Galaxies with the Nancy Grace Roman Space Telescope

    Publication
    Stellar streams form through the tidal disruption of satellite galaxies or globular clusters orbiting a host galaxy. Globular cluster streams are exciting since they are thin (dynamically cold …

  4. Constraining the length and pattern speed of the Milky Way bar from direct orbit integration of APOGEE and Gaia data

    Publication
    The dynamics of the inner Galaxy contain crucial clues for untangling the evolutionary history of the Milky Way. However, the inner Galaxy's gravitational potential is poorly constrained …

  5. Mapping Dark Matter with Extragalactic Stellar Streams: the Case of Centaurus A

    Publication
    In the coming decade, thousands of stellar streams will be observed in the halos of external galaxies. What fundamental discoveries will we make about dark matter from these …

  6. The Hough Stream Spotter: A New Method for Detecting Linear Structure in Resolved Stars and Application to the Stellar Halo of M31

    Publication
    Stellar streams from globular clusters (GCs) offer constraints on the nature of dark matter and have been used to explore the dark matter halo structure and substructure of …

  7. Kinematics of the Palomar 5 stellar stream from RR Lyrae stars

    Publication

  8. Variations in the width, density, and direction of the Palomar 5 tidal tails

    Publication

  9. Detecting Thin Stellar Streams in External Galaxies: Resolved Stars & Integrated Light

    Publication

  10. Detecting Thin Stellar Streams in External Galaxies: Resolved Stars & Integrated Light

    Publication
    The morphology of thin stellar streams can be used to test the nature of dark matter. It is therefore crucial to extend searches for globular cluster streams to …
