An HST Wide Field Survey of the Galactic Bulge: Overview, Strategy, and First Results
Sean K. Terry, Jay Anderson, Charles A. Beichman +13
We present an HST imaging survey of a 1.1 sq. degree sky area toward the Milky Way Galactic Bulge. This field significantly overlaps with the upcoming Nancy Grace Roman Galactic Bu…
IRS 9: The Case for a Dynamically-Ejected Star from the Galactic Center
Matthew Hosek, Tuan Do, Smadar Naoz +7
Measuring stellar motions at the Milky Way's Galactic center (GC) provides unique insight into the dynamical processes within galactic nuclei. We present proper motion measurements…
The HST-Gaia Near-Infrared Astrometric Reference Frame near the Milky Way Galactic Center
Matthew W. Hosek, Tuan Do, Gregory D. Martinez +5
We present the first high-precision proper motion catalog, tied to the International Celestial Reference System (ICRS), of infrared astrometric reference stars within R 25"…
Structure and Dynamics of the Young Massive Star Cluster Westerlund 1
Lingfeng Wei, Matthew W. Hosek, Jessica R. Lu +8
We present a structural analysis of the young massive star cluster Westerlund 1 (Wd 1). With multi-epoch Hubble Space Telescope (HST) observations, we measure the proper motions of…
