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…

Near-Infrared Flux Distribution of Sgr A* from 2005-2022: Evidence for an Enhanced Accretion Episode in 2019

Grant C. Weldon, Tuan Do, Gunther Witzel +10

Sgr A* is the variable electromagnetic source associated with accretion onto the Galactic center supermassive black hole. While the near-infrared (NIR) variability of Sgr A* was sh…

An Updated Reference Frame for the Galactic Inner Parsec

Jeremy Darling, Jennie Paine, Mark J. Reid +3

Infrared observations of stellar orbits about Sgr A* probe the mass distribution in the inner parsec of the Galaxy and provide definitive evidence for the existence of a massive bl…

Evidence of a Decreased Binary Fraction for Massive Stars Within 20 Milliparsecs of the Supermassive Black Hole at the Galactic Center

Devin S. Chu, Tuan Do, Andrea Ghez +12

We present the results of the first systematic search for spectroscopic binaries within the central 2 x 3 arcsec around the supermassive black hole at the center of the Milky W…

The Swansong of the Galactic Center Source X7: An Extreme Example of Tidal Evolution near the Supermassive Black Hole

Anna Ciurlo, Randall D. Campbell, Mark R. Morris +14

We present two decades of new high-angular-resolution near-infrared data from the W. M. Keck Observatory that reveal extreme evolution in X7, an elongated dust and gas feature, pre…

Search for a Variation of the Fine Structure around the Supermassive Black Hole in Our Galactic Center

A. Hees, T. Do, B. M. Roberts +11

Searching for space-time variations of the constants of Nature is a promising way to search for new physics beyond General Relativity and the standard model motivated by unificatio…
