Chandra Multiwavelength Project X-ray Point Source Catalog

Minsun Kim, Dong-Woo Kim, Belinda J. Wilkes +13

We present the Chandra Multiwavelength Project (ChaMP) X-ray point source catalog with ~6,800 X-ray sources detected in 149 Chandra observations covering \~10 deg^2. The full ChaMP…

Co-moving space density of X-ray-selected Active Galactic Nuclei

J. D. Silverman, P. J. Green, W. A. Barkhouse +11

For measurement of the AGN luminosity function and its evolution, X-ray selection samples all types of AGN and provides reduced obscuration bias in comparison with UV-excess or opt…

X-Ray and Optical Variability in NGC 4051 and the Nature of Narrow-Line Seyfert 1 Galaxies

B. M. Peterson, I. M. McHardy, B. J. Wilkes +14

We report on the results of a three-year program of coordinated X-ray and optical monitoring of the narrow-line Seyfert 1 galaxy NGC 4051. The rapid continuum variations observed i…

[OII] Emission, Eigenvector 1 and Orientation in Radio-quiet Quasars

J. Kuraszkiewicz, B. J. Wilkes, W. N. Brandt +1

We present supportive evidence that the Boroson and Green eigenvector 1 is not driven by source orientation. Until recently it was generally accepted that eigenvector 1 does not de…

The Chandra X-ray Observatory Resolves the X-ray Morphology and Spectra of a Jet in PKS 0637-752

G. Chartas, D. M. Worrall, M. Birkinshaw +14

The core-dominated radio-loud quasar PKS 0637-752 (z = 0.654) was the first celestial object observed with the Chandra X-ray Observatory, offering the early surprise of the detecti…

Multiwavelength observations of short time-scale variability in NGC 4151. I. Ultraviolet observations

D. M. Crenshaw et al

We present the results of an intensive ultraviolet monitoring campaign on the Seyfert 1 galaxy NGC 4151, as part of an effort to study its short time-scale variability over a broad…
