Improving Galactic Center Astrometry by Reducing the Effects of Geometric Distortion
Sylvana Yelda, Jessica R. Lu, Andrea M. Ghez +4
We present significantly improved proper motion measurements of the Milky Way's central stellar cluster. These improvements are made possible by refining our astrometric reference…
Recent Results and Perspectives for Precision Astrometry and Photometry with Adaptive Optics
Jessica R. Lu, Andrea M. Ghez, Sylvana Yelda +4
Large ground-based telescopes equipped with adaptive optics (AO) systems have ushered in a new era of high-resolution infrared photometry and astrometry. Relative astrometric accur…
Disks in the Arches cluster -- survival in a starburst environment
Andrea Stolte, Mark Morris, Andrea Ghez +6
Deep Keck/NIRC2 HK'L' observations of the Arches cluster near the Galactic center reveal a significant population of near-infrared excess sources. We combine the L'-band excess obs…
Testing stellar cusp formation theories with observations of the Milky Way nuclear star cluster
Tuan Do, Andrea M. Ghez, Mark R. Morris +5
(Abridged) We report on the structure of the nuclear star cluster in the innermost 0.16 pc of the Galaxy as measured by the number density profile of late-type giants. Using laser…
Increasing the Scientific Return of Stellar Orbits at the Galactic Center
Sylvana Yelda, Andrea M. Ghez, Jessica R. Lu +3
We report a factor of 3 improvement in Keck Laser Guide Star Adaptive Optics (LGSAO) astrometric measurements of stars near the Galaxy's supermassive black hole (SMBH). By ca…
