cds-question@unistra.frseyfert-galaxiesactive-galactic-nucleiredshiftedgalaxy-kinematicsspectroscopyWe create a baseline of the black hole (BH) mass (M_BH_)-stellar-velocity dispersion ({sigma}) relation for active galaxies, using a sample of 66 local (0.02<z<0.09) Seyfert-1 galaxies, selected from the Sloan Digital Sky Survey (SDSS). Analysis of SDSS images yields AGN luminosities free of host-galaxy contamination, and morphological classification. 51/66 galaxies have spiral morphology. Out of these, 28 bulges have Sersic index n<2 and are considered candidate pseudo-bulges, with eight being definite pseudo-bulges based on multiple classification criteria met. Only 4/66 galaxies show signs of interaction/merging. High signal-to-noise ratio Keck spectra provide the width of the broad H{beta} emission line free of Fe II emission and stellar absorption. AGN luminosity and H{beta} line widths are used to estimate M_BH_. The Keck-based spatially resolved kinematics is used to determine stellar-velocity dispersion within the spheroid effective radius ({sigma}_spat,reff_). We find that {sigma} can vary on average by up to 40% across definitions commonly used in the literature, emphasizing the importance of using self-consistent definitions in comparisons and evolutionary studies. The M_BH_-{sigma} relation for our Seyfert-1 galaxy sample has the same intercept and scatter as that of reverberation-mapped AGNs as well as that of quiescent galaxies, consistent with the hypothesis that our single epoch M_BH_ estimator and sample selection function do not introduce significant biases. Barred galaxies, merging galaxies, and those hosting pseudo-bulges do not represent outliers in the M_BH_-{sigma} relation. This is in contrast with previous work, although no firm conclusion can be drawn on this matter due to the small sample size and limited resolution of the SDSS images.2015ApJ...809...20Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/809/20CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/294 : The SDSS Photometric Catalog, Release 7J/ApJ/596/437 : Stellar-mass black holes in the SDSS (Chisholm+, 2003)J/ApJ/641/L21 : Black hole mass and velocity dispersion relationJ/ApJ/667/131 : Mass function of active black holes (Greene+, 2007)J/ApJS/201/29 : Velocity dispersions in active galaxies (Harris+, 2012)J/ApJ/831/134 : BH masses + host galaxy dispersion vel.
