The Galactic Center with Roman

Sean K. Terry, Matthew W. Hosek, Jessica R. Lu +31

We advocate for a Galactic center (GC) field to be added to the Galactic Bulge Time Domain Survey (GBTDS). The new field would yield high-cadence photometric and astrometric measur…

On Socially Distant Neighbors: Using Binaries to Constrain the Density of Objects in the Galactic Center

Sanaea C. Rose, Smadar Naoz, Abhimat K. Gautam +4

Stars often reside in binary configurations. The nuclear star cluster surrounding the supermassive black hole (SMBH) in the Galactic Center (GC) is expected to include a binary pop…

A Kinematic Study of Wolf-Rayet Stars at the Galactic Center I: Binary Candidates and Constraints on the Binary Fraction

Rory O. Bentley, Tuan Do, Andrea Ghez +13

We report the binary fraction of Wolf-Rayet (WR) stars within 0.5~pc of the Galactic center obtained through the longest time-baseline (1994-2024) kinematic study of this populatio…

The Star Formation History of the Milky Way's Nuclear Star Cluster

Zhuo Chen, Tuan Do, Andrea M. Ghez +6

We report the first star formation history study of the Milky Way's nuclear star cluster (NSC) that includes observational constraints from a large sample of stellar metallicity me…

Characterizing and Improving the Data Reduction Pipeline for the Keck OSIRIS Integral Field Spectrograph

Kelly E. Lockhart, Tuan Do, James E. Larkin +15

OSIRIS is a near-infrared (1.0--2.4 m) integral field spectrograph operating behind the adaptive optics system at Keck Observatory, and is one of the first lenslet-based integr…
