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…

Optical Variability of Narrow-Line Seyfert 1 Galaxies

Elizabeth S. Klimek, C. Martin Gaskell, Cecelia H. Hedrick

We present results of a broad-band photometric study of the optical variability of six Narrow-Line Seyfert 1 (NLS1) galaxies observed at 172 epochs. We searched for microvariabilit…
