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…

Constraining a companion of the galactic center black hole, Sgr A*

Clifford M. Will, Smadar Naoz, Aurélien Hees +4

We use 23 years of astrometric and radial velocity data on the orbit of the star S0-2 to constrain a hypothetical intermediate-mass black hole orbiting the massive black hole Sgr A…

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…
