Design and development of NIRSPEC: a near-infrared echelle spectrograph for the Keck II telescope
The design and development of NIRSPEC, a near-IR echelle spectrograph for the Keck II 10-meter telescope is described. This instrument is a large, facility-class vacuum-cryogenic spectrometer with aExpand
The First Measurement of Spectral Lines in a Short-Period Star Bound to the Galaxy’s Central Black Hole: A Paradox of Youth
We have obtained the first detection of spectral absorption lines in one of the high-velocity stars in the vicinity of the Galaxy's central supermassive black hole. Both Brγ (2.1661 μm) and He IExpand
We present the results of a spectroscopic survey of the kinematic structure of star-forming galaxies at redshift z ∼ 2–3 using Keck/OSIRIS integral field spectroscopy. Our sample is comprised of 12Expand
Massive Stars in the Arches Cluster
We present and use new spectra and narrowband images, along with previously published broadband images, of stars in the Arches cluster to extract photometry, astrometry, equivalent width, andExpand
Detection and Characterization of Exoplanets and Disks using Projections on Karhunen-Loeve Eigenimages
We describe a new method to achieve point spread function (PSF) subtractions for high- contrast imaging using Principal Component Analysis (PCA) that is applicable to both point sources or extendedExpand
The external shear acting on gravitational lens B1422+231
In a number of multiply imaged quasar systems, a significant contribution to the lensing potential is provided by groups and clusters of galaxies associated with the primary lens. As part of anExpand
First Light Adaptive Optics Images from the Keck II Telescope : A New Era of High Angular Resolution Imagery
ABSTRACT Adaptive optics (AO) is a technology that corrects in real time for the blurring effects of atmospheric turbulence, in principle allowing Earth‐bound telescopes to achieve their diffractionExpand
OSIRIS: A diffraction limited integral field spectrograph for Keck
Abstract We present an overview of the OSIRIS integral field spectrograph which was recently commissioned on the Keck II Telescope. OSIRIS works with the Keck Adaptive Optics system and utilizes anExpand
Dynamics of Galactic Disks and Mergers at z ~ 1.6: Spatially Resolved Spectroscopy with Keck Laser Guide Star Adaptive Optics
We present 0".2 resolution near-infrared integral field spectroscopy of Hα emission from six star-forming galaxies at z ~ 1.6 (a look-back time of ~9.6 Gyr). These observations were obtained withExpand
Performance and results with the NIRSPEC echelle spectrograph on the Keck II telescope
This paper describes the performance of NIRSPEC, the cryogenic cross-dispersed IR echelle spectrograph for the Keck II telescope on Mauna Kea. NIRSPEC employs a 1024 by 1024 InSb array,Expand
