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…
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…
Tidal phenomena in the Galactic Center: The curious case of X7
Wasif Shaqil, Diego Calderón, Stephan Rosswog +5
Several enigmatic dusty sources have been detected in the central parsec of the Galactic Center. Among them is X7, located at only 0.02 pc from the central super-massive blac…
Sagittarius A* -- The Milky Way Supermassive Black Hole
Anna Ciurlo, Mark R. Morris
This chapter provides a detailed overview of Sagittarius A* (Sgr A*), the supermassive black hole at the center of the Milky Way, located in the dense Galactic Center region approx…
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…
