The Weak Outnumbering the Mighty: Normal Galaxies in Deep Chandra Surveys
A. E. Hornschemeier, F. E. Bauer, D. M. Alexander +5
Chandra is detecting a significant population of normal and starburst galaxies in extremely deep X-ray exposures. For example, approximately 15% of the sources arising in the 2 Ms…
Resolving the Source Populations that Contribute to the X-ray Background: The 2 Ms Chandra Deep Field-North Survey
D. M. Alexander, F. E. Bauer, W. N. Brandt +4
With ~2 Ms of Chandra exposure, the Chandra Deep Field-North (CDF-N) survey provides the deepest view of the Universe in the 0.5-8.0 keV band. Five hundred and three (503) X-ray so…
The Chandra Deep Field-North Survey. XIV. X-ray detected Obscured AGNs and Starburst Galaxies in the Bright Submm Source Population
D. M. Alexander, F. E. Bauer, W. N. Brandt +6
We provide X-ray constraints and perform the first X-ray spectral analyses for bright (f_850>=5mJy; S/N>=4) SCUBA sources in an 8.4'x8.4' area of the 2 Ms Chandra Deep Field-North…
The AGN Source Population in the Chandra Deep Field-North Survey: Constraints from X-ray Spectroscopy and Variability
F. E. Bauer, C. Vignali, D. M. Alexander +6
We briefly report here on our ongoing X-ray spectroscopy and variability analyses of 136 faint X-ray sources discovered in the 2 Ms Chandra Deep Field North observations spanning 1…
X-rays from the High-Redshift Universe: The Chandra view
C. Vignali, W. N. Brandt, D. P. Schneider +4
The study of the X-ray properties of z>4 quasars has grown substantially over the last few years, mostly thanks to Chandra. Here we focus on (1) the average X-ray properties of an…
The Chandra Deep Field North Survey. XII. The Link Between Faint X-ray and Radio Source Populations
F. E. Bauer, D. M. Alexander, W. N. Brandt +4
We investigate the relationship between faint X-ray and 1.4 GHz radio source populations detected within 3' of the Hubble Deep Field North using the 1 Ms Chandra and 40 uJy VLA sur…
