The X-ray Properties of Early-Type Galaxies in the Extended Chandra Deep Field-South
B. D. Lehmer, W. N. Brandt, D. M. Alexander +8
We investigate the evolution over the last 6.3 Gyr of cosmic time (i.e., since z ~ 0.7) of the average X-ray properties of early-type galaxies within the Extended Chandra Deep Fiel…
Can the unresolved X-ray background be explained by emission from the optically-detected faint galaxies of the GOODS project?
M. A. Worsley, A. C. Fabian, F. E. Bauer +3
The emission from individual X-ray sources in the Chandra Deep Fields and XMM-Newton Lockman Hole shows that almost half of the hard X-ray background above 6 keV is unresolved and…
The X-ray-to-Optical Properties of Optically-Selected Active Galaxies Over Wide Luminosity and Redshift Ranges
A. T. Steffen, I. Strateva, W. N. Brandt +5
We present partial-correlation analyses that examine the strengths of the relationships between L_UV, L_X, Alpha_OX, and redshift for optically-selected AGNs. We extend the work of…
The Properties and Redshift Evolution of Intermediate-Luminosity Off-Nuclear X-ray Sources in the Chandra Deep Fields
B. D. Lehmer, W. N. Brandt, A. E. Hornschemeier +5
We analyze a population of intermediate-redshift (z ~ 0.05-0.3), off-nuclear X-ray sources located within optically-bright galaxies in the Great Observatories Origins Deep Survey (…
