Reverberation Mapping of High-Luminosity Quasars: First Results
Shai Kaspi, W. N. Brandt, Dan Maoz +3
Reverberation mapping of nearby active galactic nuclei has led to estimates of broad-line-region (BLR) sizes and central-object masses for some 37 objects to date. However, success…
Model Atmosphere Analysis of the Weakly Magnetic DZ White Dwarf G165-7
P. Dufour, P. Bergeron, G. D. Schmidt +5
A reanalysis of the strongly metal-blanketed DZ white dwarf G165-7 is presented. An improved grid of model atmospheres and synthetic spectra is used to analyze BVRI, JHK, and ugriz…
The Properties and Redshift Evolution of Intermediate-Luminosity Off-Nuclear X-ray Sources in the Chandra Deep Fields
B. D. Lehmer, W. N. Brandt, A. E. Hornschemeier +5
We analyze a population of intermediate-redshift (z ~ 0.05-0.3), off-nuclear X-ray sources located within optically-bright galaxies in the Great Observatories Origins Deep Survey (…
A Chandra Snapshot Survey of Representative High-Redshift Radio-Loud Quasars from the Parkes-MIT-NRAO Sample
L. A. Lopez, W. N. Brandt, C. Vignali +3
We present the results of Chandra ACIS-S snapshot observations of six radio-loud quasars (RLQs) at z=3.5-4.7. These observations sample luminous RLQs with moderate-to-high radio-lo…
