Integral Field Spectroscopy of a Candidate Disk Galaxy at z~1.5 using Laser Guide Star Adaptive Optics
S. A. Wright, J. E. Larkin, M. Barczys +8
We present 0.1" resolution near-infrared integral field spectroscopy of Halpha in a z=1.4781 star forming galaxy, Q2343-BM133. These observations were obtained with OSIRIS (OH Supp…
A New Brown Dwarf Desert? A Scarcity of Wide Ultracool Binaries
Peter R. Allen, David W. Koerner, Michael W. McElwain +2
We present the results of a deep-imaging search for wide companions to low-mass stars and brown dwarfs using NSFCam on IRTF. We searched a sample of 132 M7-L8 dwarfs to magnitude l…
First High-Contrast Science with an Integral Field Spectrograph: the Sub-Stellar Companion to GQ Lup
Michael W. McElwain, Stanimir A. Metchev, James E. Larkin +6
We present commissioning data from the OSIRIS integral field spectrograph (IFS) on the Keck II 10 m telescope that demonstrate the utility of adaptive optics IFS spectroscopy in st…
Characterization of Dusty Debris Disks: the IRAS and Hipparcos Catalogs
Joseph H. Rhee, Inseok Song, B. Zuckerman +1
Dusty debris disks around main-sequence stars are signposts for the existence of planetesimals and exoplanets. From cross-correlating \hip stars with the \iras catalogs, we identif…
Resolved Spectroscopy of M Dwarf/L Dwarf Binaries. II. 2MASS J 17072343-0558249AB
Michael W. McElwain, Adam J. Burgasser
We present IRTF SpeX observations of the M/L binary system 2MASS J17072343-0558249. SpeX imaging resolves the system into a 1"01+/-0.17 visual binary in which both components have…
Diffraction Limited Imaging Spectroscopy of the SgrA* Region using OSIRIS, a new Keck Instrument
A. Krabbe, C. Iserlohe, J. E. Larkin +5
We present diffraction limited spectroscopic observations of an infrared flare associated with the radio source SgrA*. These are the first results obtained with OSIRIS, the new fac…
