Statistical Properties of Multi-epoch Spectral Variability of SDSS Stripe82 Quasars
Mitsuru Kokubo, Tomoki Morokuma, Takeo Minezaki +4
We investigate the UV-optical (longward of Ly 1216Å) spectral variability of nearly 9000 quasars () using multi-epoch photometric data within the SDSS Stripe 82 region. T…

Near-Infrared Reverberation by Dusty Clumpy Tori in Active Galactic Nuclei
Toshihiro Kawaguchi, Masao Mori
According to recent models, the accretion disk and black hole in active galactic nuclei are surrounded by a clumpy torus. We investigate the NIR flux variation of the torus in resp…

Orientation Effects on the Inner Region of Dusty Torus of Active Galactic Nuclei
Toshihiro Kawaguchi, Masao Mori
A sublimation process governs the innermost region of the dusty torus of active galactic nuclei. However, the observed inner radius of the torus is systematically smaller than the…
