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…

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…

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…

Stellar Populations in the Central 0.5 pc of Our Galaxy III: The Dynamical Sub-structures

Siyao Jia, Ningyuan Xu, Jessica R. Lu +12

We measure the 3D kinematic structures of the young stars within the central 0.5 parsec of our Galactic Center using the 10 m telescopes of the W.~M.~Keck Observatory over a time s…

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…

New multiple AGN systems with sub-arcsec separation: confirmation of candidates selected via the novel GMP method

A. Ciurlo, F. Mannucci, S. Yeh +18

The existence of multiple active galactic nuclei (AGN) at small projected distances on the sky is due to either the presence of multiple, in-spiraling SMBHs, or to gravitational le…
