Observing Strategies for the NICI Campaign to Directly Image Extrasolar Planets
Beth Biller, Etienne Artigau, Zahed Wahhaj +7
We discuss observing strategy for the Near Infrared Coronagraphic Imager (NICI) on the 8-m Gemini South telescope. NICI combines a number of techniques to attenuate starlight and s…
Performance of the Near-infrared coronagraphic imager on Gemini-South
Mark Chun, Doug Toomey, Zahed Wahhaj +8
We present the coronagraphic and adaptive optics performance of the Gemini-South Near-Infrared Coronagraphic Imager (NICI). NICI includes a dual-channel imager for simultaneous spe…
NICI: combining coronagraphy, ADI, and SDI
Etienne Artigau, Beth A. Biller, Zahed Wahhaj +9
The Near-Infrared Coronagraphic Imager (NICI) is a high-contrast AO imager at the Gemini South telescope. The camera includes a coronagraphic mask and dual channel imaging for Spec…
CATS: Optical to Near-Infrared Colors of the Bulge and Disk of Two z=0.7 Galaxies Using HST and Keck Laser Adaptive Optics Imaging
E. Steinbring, J. Melbourne, A. J. Metevier +5
We have employed laser guide star (LGS) adaptive optics (AO) on the Keck II telescope to obtain near-infrared (NIR) images in the Extended Groth Strip (EGS) deep galaxy survey fiel…
LOLAS: an optical turbulence profiler in the atmospheric boundary layer with extreme altitude-resolution
R. Avila, J. L. Aviles, R. W. Wilson +3
We report the development and first results of an instrument called Low Layer Scidar (LOLAS) which is aimed at the measurement of optical-turbulence profiles in the atmospheric bou…
Adaptive Optics Imaging of Low-redshift Damped Lyman-alpha Quasar Absorbers
Mark R. Chun, Soheila Gharanfoli, Varsha P. Kulkarni +1
We have carried out a high angular resolution near-infrared imaging study of the fields of 6 quasars with 7 strong absorption line systems at z < 0.5, using the Hokupa'a adaptive o…
