The Cosmic Evolution of Hard X-ray Selected Active Galactic Nuclei
A. J. Barger, L. L. Cowie, R. F. Mushotzky +4
We use highly spectroscopically complete deep and wide-area Chandra surveys to determine the cosmic evolution of hard X-ray-selected AGNs. We determine hard X-ray luminosity functi…
An Optical Catalog of the Chandra Large Area Synoptic X-ray Survey Sources
A. T. Steffen, A. J. Barger, P. Capak +3
We present photometric and spectroscopic observations of the X-ray sources detected in the wide-area, moderately deep Chandra Large Area Synoptic X-ray Survey of the Lockman Hole-N…
An 850 Micron SCUBA Survey of the HDF-N GOODS Region
W. -H. Wang, L. L. Cowie, A. J. Barger
The Hubble Deep Field-North (HDF-N) is one of the best studied extragalactic fields, and ultra-deep optical, radio, X-ray, and mid-infrared wide-field images are available for this…
A large sample of spectroscopic redshifts in the ACS-GOODS region of the HDF-N
L. L. Cowie, A. J. Barger, E. M. Hu +2
We report the results of an extensive spectroscopic survey of galaxies in the roughly 160 square arcminute ACS-GOODS region surrounding the HDF-N. We have identified 787 galaxies o…
