I direct a laboratory for the construction of cryogenic near-infrared detection systems. Instruments developed in recent years include the 256 × 256 element NICMOS3 HgCdTe camera (NICMASS), the 2MASS cameras, the CorMASS near-infrared spectrograph, the R=3000 TripleSpec spectrograph which is a facility instrument at Apache Point Observatory and the APOGEE . One of the 2MASS cameras remains active at the PAIRITEL automated infrared telescope facility at Mt. Hopkins, Arizona providing observers in the department quick access to automated observations of the near-infrared sky. The other 2MASS camera operates at the Kuiper 61" Telescope at Mt. Bigelow, Az, also available to department members through our allocation of time at Steward Observatory facilities. Beyond facilitating my research interests, this laboratory is intended to provide graduate students and undergraduates with hands-on experience with astronomical instrumentation. Current lab efforts include the operation and scientific use of Fan Mountain Infrared Camera operating at UVa's 31-inch telescope at Fan Mountain Observatory. This camera was designed, constructed and commissioned by students in the department. The laboratory has recently completed a mid-infrared (3-5um) imaging channel, LMIRcam, to support the University of Arizona's imaging interferometer at the Large Binocular Telescope. This instrument hold the exciting prospect of delivering 30 millarcsecond spatial resolution in the thermal infrared enabling direct imaging and spectroscopy of warm Jupiter analogs orbiting several AU from nearby stars. In parallel the laboratory has designed, fabricated and commissioned its most ambitious instrument to date - a 300-fiber high-resolution (R=22,000) 1.5-1.7um cryogenic spectrograph that is now conducting the APOGEE survey for the third-generation Sloan Digital Sky Survey (SDSS-III). The spectrograph will measure the elemental abundances in 100,000 Milky Way giant stars providing a window on the assembly history of the Milky Way.

The laboratory also maintains facilities to test and characterize infrared arrays. For the last few years we have pursued an NSF-funded program with Goodrich Corporation - Sensors Unlimited to develop and evaluate extended wavelength (2.3um cutoff) InGaAs arrays capable of matching the performance of HgCdTe arrays in ground-based applications. This work has lead to the production of an extended InGaAs array bonded to a cryogenic "astronomical" multiplexer and has been tested in the CorMASS spectrograph.

Mr. Skrutskie directs a laboratory for the construction and application of instruments operating at near-infrared (1-5um) wavelengths. He was the principal investigator of the Two Micron All Sky Survey (2MASS) and is now deeply involved in the space-based mid-infrared equivalent, WISE. Common scientific themes for both missions are the detection and characterization of sub-stellar objects (brown dwarfs) and delineating the structure of the Milky Way. The laboratory has recently delivered instruments for the world's largest telescope, the Large Binocular Telescope, and for the Sloan Digital Sky Survey.
