A Deep, Wide Field, Optical, and Near Infrared Catalog of a Large Area around the Hubble Deep Field North
P. Capak, L. L. Cowie, E. M. Hu +10
We have conducted a deep multi-color imaging survey of 0.2 degrees^2 centered on the Hubble Deep Field North (HDF-N). We shall refer to this region as the Hawaii-HDF-N. Deep data w…
Faint 6.7um Galaxies and their Contributions to the Stellar Mass Density in the Universe
Yasunori Sato, Lennox L. Cowie, Kimiaki Kawara +6
We discuss the nature of faint 6.7um galaxies detected with the mid-infrared camera ISOCAM on board the Infrared Space Observatory (ISO). The 23 hour integration on the Hawaii Deep…
The Luminosity Function of Lyman Alpha Emitters at Redshift z~5.7
Esther M. Hu, Lennox L. Cowie, Peter Capak +3
We report results of a deep wide-field narrowband survey for redshift z~5.7 Ly alpha emitters carried out with SuprimeCam on Subaru 8.3-m telescope. Deep narrowband imaging of the…
The Changing AGN Population
A. T. Steffen, A. J. Barger, L. L. Cowie +2
We investigate how the fraction of broad-line sources in the AGN population changes with X-ray luminosity and redshift. We first construct the rest-frame hard-energy (2-8 keV) X-ra…
A deep 6.7um survey in the SSA13 field with ISO
Y. Sato, K. Kawara, L. L. Cowie +8
We present results of a deep mid-infrared survey in the SSA13 field with the Infrared Space Observatory (ISO). In order to probe the near-infrared light at high redshifts, we surve…
Optical and Infrared Properties of the 2 Ms Chandra Deep Field-North X-ray Sources
A. J. Barger, L. L. Cowie, P. Capak +6
We present an optical and NIR catalog for the X-ray sources in the 2 Ms Chandra observation of the Hubble Deep Field-North region. We have high-quality multicolor images of all 503…
