Tracing the Mass-Dependent Star Formation History of Late-Type Galaxies using X-ray Emission: Results from the Chandra Deep Fields
B. D. Lehmer, W. N. Brandt, D. M. Alexander +11
We report on the X-ray evolution over the last ~9 Gyr of cosmic history (i.e., since z = 1.4) of late-type galaxy populations in the Chandra Deep Field-North and Extended Chandra D…
Confirmation of a correlation between the X-ray luminosity and spectral slope of AGNs in the Chandra Deep Fields
C. Saez, G. Chartas, W. N. Brandt +4
We present results from a statistical analysis of 173 bright radio-quiet AGNs selected from the Chandra Deep Field-North and Chandra Deep Field-South surveys (hereafter, CDFs) in t…
The Evolution of AGN Host Galaxies: From Blue to Red and the Influence of Large-Scale Structures
J. D. Silverman, V. Mainieri, B. D. Lehmer +14
We present an analysis of 109 moderate-luminosity (41.9 < Log L{0.5-8.0 keV} < 43.7) AGN in the Extended Chandra Deep Field-South survey, which is drawn from 5,549 galaxies from th…
Ly-alpha Emission-Line Galaxies at z = 3.1 in the Extended Chandra Deep Field South
C. Gronwall, R. Ciardullo, T. Hickey +13
We describe the results of an extremely deep, 0.28 deg^2 survey for z = 3.1 Ly-alpha emission-line galaxies in the Extended Chandra Deep Field South. By using a narrow-band 5000 An…
Chandra Stacking Constraints on the Contribution of 24 micron Spitzer Sources to the Unresolved Cosmic X-ray Background
A. T. Steffen, W. N. Brandt, D. M. Alexander +2
We employ X-ray stacking techniques to examine the contribution from X-ray undetected, mid-infrared-selected sources to the unresolved, hard (6-8 keV) cosmic X-ray background (CXB)…
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…
