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…
The infrared imaging spectrograph (IRIS) for TMT: the science case
Elizabeth J. Barton, James E. Larkin, Anna M. Moore +11
The InfraRed Imaging Spectrograph (IRIS) is a first-light instrument being designed for the Thirty Meter Telescope (TMT). IRIS is a combination of an imager that will cover a 16.4"…
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…
