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…
The Chandra Large Area Synoptic X-ray Survey (CLASXS) of the Lockman Hole-Northwest: The X-ray Catalog
Y. Yang, R. F. Mushotzky, A. T. Steffen +2
We present the X-ray catalog and basic results from our Chandra Large Area Synoptic X-ray Survey (CLASXS) of the Lockman Hole-Northwest field. Our 9 ACIS-I fields cover a contiguou…
The Team Keck Treasury Redshift Survey of the GOODS-North Field
Gregory D. Wirth, Christopher N. A. Willmer, Paola Amico +19
We report the results of an extensive imaging and spectroscopic survey in the GOODS-North field completed using DEIMOS on the Keck II telescope. Observations of 2018 targets in a m…
The Evolution of the Ultraluminous Infrared Galaxy Population from Redshift 0 to 1.5
L. L. Cowie, A. J. Barger, E. B. Fomalont +1
We use redshift observations of two deep 1.4GHz fields to probe the evolution of the bright end of the radio galaxy luminosity function to z=1.5. We show that the number of galaxie…
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…
