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…
Calibration of AGN Reverberation Distance Measurements
Shintaro Koshida, Yuzuru Yoshii, Yukiyasu Kobayashi +6
In Yoshii et al. (2014), we described a new method for measuring extragalactic distances based on dust reverberation in active galactic nuclei (AGNs), and we validated our new meth…
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…
A New Method for Measuring Extragalactic Distances
Y. Yoshii, Y. Kobayashi, T. Minezaki +2
We have pioneered a new method for the measurement of extragalactic distances. This method uses the time-lag between variations in the short wavelength and long wavelength light fr…
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…
Long-Term Optical Continuum Color Variability of Nearby Active Galactic Nuclei
Yu Sakata, Takeo Minezaki, Yuzuru Yoshii +8
We examine whether the spectral energy distribution of optical continuum emission of active galactic nuclei (AGNs) changes during flux variation, based on accurate and frequent mon…
