The Post-Periapse Evolution of Galactic Center Source G1: The second case of a resolved tidal interaction with a supermassive black hole
Gunther Witzel, Breann. N. Sitarski, Andrea M. Ghez +13
We present new Adaptive Optics (AO) imaging and spectroscopic measurements of Galactic Center source G1 from W. M. Keck Observatory. Our goal is to understand its nature and relati…
Testing the gravitational theory with short-period stars around our Galactic Center
A. Hees, A. M. Ghez, T. Do +19
Motion of short-period stars orbiting the supermassive black hole in our Galactic Center has been monitored for more than 20 years. These observations are currently offering a new…
IRS 16SW - A New Comoving Group of Young Stars in the Central Parsec of the Milky Way
J. R. Lu, A. M. Ghez, S. D. Hornstein +2
One of the most perplexing problems associated with the supermassive black hole at the center of our Galaxy is the origin of the young stars in its close vicinity. Using proper mot…
An Overabundance of Transient X-ray Binaries within 1 pc of the Galactic Center
M. P. Muno, E. Pfahl, F. K. Baganoff +4
During five years of Chandra observations, we have identified seven X-ray transients located within 23 pc of Sgr A*. These sources each vary in luminosity by more than a factor of…
