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…
Reverberation Mapping Measurements of Black Hole Masses in Six Local Seyfert Galaxies
K. D. Denney, B. M. Peterson, R. W. Pogge +40
We present the final results from a high sampling rate, multi-month, spectrophotometric reverberation mapping campaign undertaken to obtain either new or improved Hbeta reverberati…
The Lick AGN Monitoring Project: Reverberation Mapping of Optical Hydrogen and Helium Recombination Lines
Misty C. Bentz, Jonelle L. Walsh, Aaron J. Barth +23
We have recently completed a 64-night spectroscopic monitoring campaign at the Lick Observatory 3-m Shane telescope with the aim of measuring the masses of the black holes in 12 ne…
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…
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…
The Lick AGN Monitoring Project: Photometric Light Curves and Optical Variability Characteristics
Jonelle L. Walsh, Takeo Minezaki, Misty C. Bentz +16
The Lick AGN Monitoring Project targeted 13 nearby Seyfert 1 galaxies with the intent of measuring the masses of their central black holes using reverberation mapping. The sample i…
Diverse Broad Line Region Kinematic Signatures From Reverberation Mapping
K. D. Denney, B. M. Peterson, R. W. Pogge +40
A detailed analysis of the data from a high sampling rate, multi-month reverberation mapping campaign, undertaken primarily at MDM Observatory with supporting observations from tel…
The Lick AGN Monitoring Project: Broad-Line Region Radii and Black Hole Masses from Reverberation Mapping of Hbeta
Misty C. Bentz, Jonelle L. Walsh, Aaron J. Barth +24
We have recently completed a 64-night spectroscopic monitoring campaign at the Lick Observatory 3-m Shane telescope with the aim of measuring the masses of the black holes in 12 ne…
Variation of Inner Radius of Dust Torus in NGC4151
Shintaro Koshida, Yuzuru Yoshii, Yukiyasu Kobayashi +8
The long-term optical and near infrared monitoring observations for a type 1 act ive galactic nucleus NGC 4151 were carried out for six years from 2001 to 2006 b y using the MAGNUM…
