The Lick AGN Monitoring Project: The MBH - sigma Relation For Reverberation-Mapped Active Galaxies
Jong-Hak Woo, Tommaso Treu, Aaron J. Barth +13
(Abridged) To investigate the black hole mass (MBH) vs. stellar velocity dispersion relation of active galaxies, we measured the velocity dispersions of a sample of local Seyfert 1…
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…
