Structure and Kinematics of the Broad-Line Region and Torus of Active Galactic Nuclei
C. Martin Gaskell, Rene W. Goosmann, Elizabeth S. Klimek
Energetics considerations imply that the broad-line region (BLR) has a high covering factor. The absence of absorption from the BLR means that the BLR has to have a flattened distr…
NGC 5548: The AGN Energy Budget Problem and the Geometry of the Broad-Line Region and Torus
C. Martin Gaskell, Elizabeth S. Klimek, Ludmila S. Nazarova
We consider in detail the spectral energy distribution (SED) and multi-wavelength variability of NGC5548. Comparison with the SEDs of other AGNs implies that the internal reddening…
Optical Variability of the Three Brightest Nearby Quasars
C. Martin Gaskell, Andrew J. Benker, Jeffrey S. Campbell +9
We report on the relative optical variability of the three brightest nearby quasars, 3C 273, PDS 456, and PHL 1811. All three have comparable absolute magnitudes, but PDS 456 and P…
