Chasing highly obscured QSOs in the COSMOS field
F. Fiore, S. Puccetti, M. Brusa +41
(abridged) We take advantage of the deep Chandra and Spitzer coverage of a large area (more than 10 times the area covered by the Chandra deep fields, CDFs in the COSMOS field, to…
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…
Deep-Survey Constraints on X-ray Outbursts from Galactic Nuclei
B. Luo, W. N. Brandt, A. T. Steffen +1
Luminous X-ray outbursts with variability amplitudes as high as ~1000 have been detected from a small number of galactic nuclei. These events are likely associated with transient f…
The X-ray Properties of the Most-Luminous Quasars from the Sloan Digital Sky Survey
D. W. Just, W. N. Brandt, O. Shemmer +4
Utilizing 21 new Chandra observations as well as archival Chandra, ROSAT, and XMM-Newton data, we study the X-ray properties of a representative sample of 59 of the most optically…
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 Realm of the First Quasars in the Universe: the X-ray View
C. Vignali, W. N. Brandt, O. Shemmer +3
We review the X-ray studies of the highest redshift quasars, focusing on the results obtained with Chandra and XMM-Newton. Overall, the X-ray and broad-band properties of z>4 quasa…
