The Keplerian orbit of G2
L. Meyer, A. M. Ghez, G. Witzel +8
We give an update of the observations and analysis of G2 - the gaseous red emission-line object that is on a very eccentric orbit around the Galaxy's central black hole and predict…
3D stellar kinematics at the Galactic center: measuring the nuclear star cluster spatial density profile, black hole mass, and distance
T. Do, G. D. Martinez, S. Yelda +6
We present 3D kinematic observations of stars within the central 0.5 pc of the Milky Way nuclear star cluster using adaptive optics imaging and spectroscopy from the Keck telescope…
Astrometry in the Galactic Center with the Thirty Meter Telescope
Sylvana Yelda, Leo Meyer, Andrea Ghez +1
We report on the expected astrometric performance of the Thirty Meter Telescope's InfraRed Imaging Spectrometer (IRIS) as determined using simulated images of the Galactic center.…
Local Group and Star Cluster Dynamics from HSTPROMO (The Hubble Space Telescope Proper Motion Collaboration)
Roeland P. van der Marel, Jay Anderson, Andrea Bellini +17
The Hubble Space Telescope (HST) has proven to be uniquely suited for the measurement of proper motions (PMs) of stars and galaxies in the nearby Universe. Here we summarize the ma…
Stellar Populations in the Central 0.5 pc of the Galaxy II: The Initial Mass Function
Jessica R. Lu, Tuan Do, Andrea M. Ghez +3
The supermassive black hole at the center of the Milky Way plays host to a massive, young cluster that may have formed in one of the most inhospitable environments in the Galaxy. W…
Stellar Populations in the Central 0.5 pc of the Galaxy I: A New Method for Constructing Luminosity Functions and Surface-Density Profiles
Tuan Do, Jessica R. Lu, Andrea M. Ghez +5
We present new high angular resolution near-infrared spectroscopic observations of the nuclear star cluster surrounding the Milky Way's central supermassive black hole. Using the i…
