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…

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…

Interstellar medium phases and abundances in the central parsec: A JWST MIRI/MRS view of the Galactic center

P. Vermot, A. Ciurlo, D. Rouan +8

We used newly obtained observations from the Mid-Infrared Instrument (MIRI) equipped with the Medium Resolution Spectrometer (MRS) aboard the James Webb Space Telescope (JWST) to e…

A multiwavelength study of the Galactic center black hole candidate MAXI J1744-294

Shifra Mandel, Kaya Mori, Paul A. Draghis +37

For the first time in nearly a decade, a bright transient was detected in the central parsec (pc) of the Galaxy. MAXI J1744-294, or -- as it was known in its previous life -- Swift…
