Reverberation Measurements of the Inner Radii of the Dust Tori in Quasars
Takeo Minezaki, Yuzuru Yoshii, Yukiyasu Kobayashi +8
We present the results of a dust-reverberation survey of quasars at redshifts z<0.6. We found a delayed response of the K-band flux variation after the optical flux variation in 25…
Reverberation Measurements of the Inner Radius of the Dust Torus in 17 Seyfert Galaxies
S. Koshida, T. Minezaki, Y. Yoshii +8
We present the results of a dust reverberation survey for 17 nearby Seyfert 1 galaxies, which provides the largest homogeneous data collection for the radius of the innermost dust…
Ultraviolet Continuum Color Variability of Luminous Sloan Digital Sky Survey QSOs
Yu Sakata, Tomoki Morokuma, Takeo Minezaki +4
We examine whether the spectral energy distribution of UV continuum emission of active galactic nuclei changes during flux variation. We used multi-epoch photometric data of QSOs i…
Twelve years of X-ray and optical variability in the Seyfert galaxy NGC 4051
E. Breedt, I. M. McHardy, P. Arevalo +7
We discuss the origin of the optical variations in the Narrow line Seyfert 1 galaxy NGC 4051 and present the results of a cross-correlation study using X-ray and optical light curv…
