Abstract
Images of the Hubble Deep Field (HDF) at 3.2 μm, taken with the 10 m Keck Telescope, are presented. The images cover a total area of ~2.5 arcmin^2. To a 5 σ limit of [3.2]_(tot) ≈ 17.5 mag (Vega relative), 11 sources are detected, nine of which are extragalactic. The integrated galaxy number counts are therefore ~1.3 × 10^4 deg^(-2) to this depth. The galaxies detected at 3.2 μm have a median redshift of z = 0.56. All 3.2 μm sources have 1.6 μm, 1.1 μm, and visual counterparts, all of fairly regular morphology; several also have 6.7 μm, 15 μm, 850 μm, 8.5 GHz, or 1.4 GHz counterparts. No sources are found that are either anomalously red or anomalously blue in their H-[3.2] color, and there are significant detections of most of the known near-infrared HDF sources for which detection in these 3.2 μm data seemed likely.

It is a pleasure to thank the P3 Team, in particular Al Conrad and Bob Goodrich, for the work on the NIRC instrument, which made this study possible, John Gathright for technical support, the HDF NICMOS General Observer team for providing near-infrared data in advance of publication, and Eric Richards for providing radio data in advance of publication. Financial support was provided by the NSF and by grants HF-01093.01-97A (Hubble Fellowship) and GO-07817.01-96A (NICMOS data) from the Space Telescope Science Institute, which is operated by AURA, Inc., under NASA contract NAS 5-26555. This research made use of the NASA ADS Abstract Service, the NOAO IRAF data reduction software, and the SM plotting software. | ||||||||||||
