A Catalog of X-ray Point Sources from Two Megaseconds of Chandra Observations of the Galactic Center
M. P. Muno, F. E. Bauer, F. K. Baganoff +23
We present a catalog of 9017 X-ray sources identified in Chandra observations of a 2 by 0.8 degree field around the Galactic center. We increase the number of known X-ray sources i…
Are Optically-Selected Quasars Universally X-Ray Luminous? X-Ray/UV Relations in Sloan Digital Sky Survey Quasars
Robert R. Gibson, W. N. Brandt, Donald P. Schneider
We analyze archived Chandra and XMM-Newton X-ray observations of 536 Sloan Digital Sky Survey (SDSS) Data Release 5 (DR5) quasars (QSOs) at 1.7 <= z <= 2.7 in order to characterize…
A Chandra Look at Five of the Broadest Double-Peaked Balmer-Line Emitters
Iskra V. Strateva, W. N. Brandt, Michael Eracleous +1
We study the 0.5-10keV emission of a sample of five of the broadest double-peaked Balmer-line emitters with Chandra. The Balmer lines of these objects originate close (within a few…
Weighing the Black Holes in z~2 Submillimeter-Emitting Galaxies Hosting Active Galactic Nuclei
D. M. Alexander, W. N. Brandt, I. Smail +7
We place direct observational constraints on the black-hole masses of the cosmologically important z~2 submillimeter-emitting galaxy (SMG; f850>4mJy) population, and use measured h…
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…
New insights into the X-ray properties of the nearby barred spiral galaxy NGC 1672
L. P. Jenkins, W. N. Brandt, E. J. M. Colbert +4
We present some preliminary results from new Chandra and XMM-Newton X-ray observations of the nearby barred spiral galaxy NGC1672. It shows dramatic nuclear and extra-nuclear star…
