Detection of Galactic Center source G2 at 3.8 m during periapse passage
Gunther Witzel, Andrea M. Ghez, Mark R. Morris +14
We report new observations of the Galactic Center source G2 from the W. M. Keck Observatory. G2 is a dusty red object associated with gas that shows tidal interactions as it nears…
Astrometric performance of the Gemini multi-conjugate adaptive optics system in crowded fields
Benoit Neichel, Jessica R. Lu, Francois Rigaut +3
The Gemini Multi-conjugate adaptive optics System (GeMS) is a facility instrument for the Gemini-South telescope. It delivers uniform, near-diffraction-limited image quality at nea…
The InfraRed Imaging Spectrograph (IRIS) for TMT: Overview of innovative science programs
Shelley A. Wright, James E. Larkin, Anna M. Moore +22
IRIS (InfraRed Imaging Spectrograph) is a first light near-infrared diffraction limited imager and integral field spectrograph being designed for the future Thirty Meter Telescope…
The orbital motion of the Quintuplet cluster - a common origin for the Arches and Quintuplet clusters?
Andrea Stolte, Benjamin Hussmann, Mark R. Morris +6
We investigate the orbital motion of the Quintuplet cluster near the Galactic center with the aim of constraining formation scenarios of young, massive star clusters in nuclear env…
