Near Infrared Imaging of the Hubble Deep Field with the Keck Telescope


Two deep K-band (2.2 ¡im) images, with point-source detection limits of K=25.2 mag (one sigma), taken with the Keck Telescope in subfields of the Hubble Deep Field, are presented and analyzed. A sample of objects to K=24 mag is constructed and V_(606)—I_(814) and I_(814)-K colors are measured. By stacking visually selected objects, mean I_(814)—K colors can be measured to very faint levels; the mean I_(814)—K color is constant with apparent magnitude down to V_(606) = 28 mag.

Additional Information

© 1997 American Astronomical Society. Received 1996 September 11; revised 1996 November 5. Based on observations obtained at the W. M. Keck Observatory, which is operated jointly by the California Institute of Technology and the University of California; and on observations obtained with the NASA/ESA Hubble Space Telescope, which is operated by AURA under NASA contract NAS 5-26555. We thank the Hubble Deep Field team, led by Bob Williams, for planning, taking, reducing, and making public the phenomenal images of the HDF. In addition, Richard Hook, Andy Fruchter, and Harry Ferguson gave us personal assistance with the HST images and catalogs. We benefited from helpful conversations with Roger Blandford, Judy Cohen, George Djorgovski, James Larkin, and Chuck Steidel and we thank the referee, David Koo, for very useful comments. We are grateful to the W. M. Keck Foundation, and particularly its president, Howard Keck, for the vision to fund the construction of the W. M. Keck Observatory. Financial support was provided by NASA through Grant No. AR-06337.13-94A from STScI, which is operated by AURA under NASA contract NAS5-26555; by the NSF through grants AST-9529170 (DWH) and AST-9157412 (MAP); and by the Bressler Foundation (MAP).
