Diffraction-limited CCD imaging with faint reference stars
R. N. Tubbs, J. E. Baldwin, C. D. Mackay +1
By selecting short exposure images taken using a CCD with negligible readout noise we obtained essentially diffraction-limited 810 nm images of faint objects using nearby reference…
The Las Campanas IR Survey: Early Type Galaxy Progenitors Beyond Redshift One
P. J. McCarthy, R. G. Carlberg, H. -W. Chen +16
(Abridged) We have identified a population of faint red galaxies from a 0.62 square degree region of the Las Campanas Infrared Survey whose properties are consistent with their bei…
The Las Campanas Infrared Survey. III. The H-band Imaging Survey and the Near-Infrared and Optical Photometric Catalogs
Hsiao-Wen Chen, P. J. McCarthy, R. O. Marzke +16
(Abridged) The Las Campanas Infrared Survey, based on broad-band optical and near-infrared photometry, is designed to robustly identify a statistically significant and representati…
Diffraction-limited 800nm imaging with the 2.56m Nordic Optical Telescope
J. E. Baldwin, R. N. Tubbs, G. C. Cox +3
A quantitative assessment is presented of diffraction-limited stellar images with Strehl ratios of 0.25-0.30 obtained by selection of short-exposure CCD images of stars brighter th…
