Optical Spectroscopy of a Candidate O-Star X-ray Binary in M33

Margaret Lazzarini, Lara Cullinane, Karoline Gilbert +8

We present new observations of a candidate O-type donor star in a high mass X-ray binary (HMXB) in M33. The candidate donor star is spatially coincident with a hard X-ray point sou…

Hubble Astrometry for the Local Group and Beyond in the 2030s

S. Tony Sohn, Paul Bennet, Kevin Andrew McKinnon +23

Hubble's long, stable astrometric baseline creates a rare opportunity for discovery in the Local Group and beyond. Many nearby galaxies, streams, and star clusters already have arc…

The Panchromatic Hubble Andromeda Southern Treasury (PHAST). II. The Spatially Resolved Recent Star Formation History in M31

Tobin M. Wainer, Benjamin F. Williams, Zhuo Chen +19

We use Hubble Space Telescope optical imaging from the Panchromatic Hubble Andromeda Southern Treasury (PHAST) to measure the spatially resolved recent star formation history (SFH)…

Unveiling Massive Main-Sequence Stars in Sextans A through Panchromatic Photometry

Maude Gull, Daniel R. Weisz, Yumi Choi +9

We present a study of the metal-poor (~6% Z_sun) massive (>8 M_sun) main-sequence star population in the star-forming dwarf galaxy Sextans A. By modeling near-UV to near-IR photome…

Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites

C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48

A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…

Kinematical Modeling of the Resolved Stellar Outskirts of M32: Constraints on Tidal Stripping Scenarios

Ivanna Escala, Douglas Grion Filho, Puragra Guhathakurta +8

As the only compact elliptical close enough to resolve into individual stars, the satellite dwarf galaxy M32 provides a unique opportunity for exploring the origins of such rare ga…
