Absolute Motion of the Infrared Counterpart to Sagittarius A* in the Gaia Celestial Reference Frame 3 and Limits on an Intermediate-mass Black Hole Companion

Rebecca A. Lewis-Merrill, Tuan Do, Matthew W. Hosek +9

We report the first proper motion and acceleration measurements of the infrared (IR) counterpart to Sagittarius A* (Sgr A*-IR), the supermassive black hole (SMBH) at the center of…

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…

First Observation of CO Emission and foreground absorption Toward the Galactic Center with JWST

J. Qiu, A. Ciurlo, M. R. Morris +11

CO is an important, stable, and abundant molecule in the Universe, but it is very difficult to detect because it has no observable pure rotational transitions. The unique sensi…

The Galactic Center in Color: Measuring Extinction with High-Proper-Motion Stars

Z. Haggard, A. M. Ghez, S. Sakai +6

The Milky Way's central parsec is a highly extinguished region with a population of high-proper-motion stars. We have tracked 145 stars for 10 years at wavelengths between 1…

An Estimate of the Binary Star Fraction Among Young Stars at the Galactic Center: Possible Evidence of a Radial Dependence

Abhimat K. Gautam, Tuan Do, Andrea M. Ghez +8

We present the first estimate of the intrinsic binary fraction of young stars across the central 0.4 pc surrounding the supermassive black hole (SMBH) at the Milky Way Ga…

High-Resolution, Mid-Infrared Color Temperature Mapping of the Central 10 Arcseconds of the Galaxy

Cuc K. Dinh, Anna Cuirlo, Mark R. Morris +3

The neighborhood of the Galactic black hole boasts a plethora of extended interstellar gas and dust features as well as populations of compact (unresolved, or marginally resolved)…
