title = "Dwarf seyfert 1 nuclei and the low-mass end of the MBH-σ relation",
abstract = "To examine the relationship between black hole mass and host galaxy velocity dispersion for low black hole masses, we have measured the velocity dispersions of 15 Seyfert 1 galaxies from the recent catalog of Greene & Ho. These Seyfert galaxies were selected from the Sloan Digital Sky Survey to have estimated black hole masses below 10 6 M⊙. The data are consistent with a straightforward downward extrapolation of the local MBH-σ relation, indicating that this correlation extends over a range of more than 4 orders of magnitude in black hole mass. The rms scatter of the sample about the extrapolated MBH-σ relation is 0.57 dex, consistent with the expected scatter of single-epoch mass estimates for Seyfert 1 galaxies.",

note = "Funding Information: We are grateful to George Djorgovski for obtaining data for this project during the 2003 November Keck observing run. We thank the referee, Brad Peterson, for helpful comments that improved this Letter. Research by A. J. B. was supported by the University of California Irvine Physical Sciences Innovation Fund and by NASA through Hubble Fellowship grant HST-HF-01134.01-A awarded by the Space Telescope Science Institute. Data presented here were obtained at the W. M. Keck Observatory, which is operated as a scientific partnership among Caltech, the University of California, and NASA. The Observatory was made possible by the generous financial support of the W. M. Keck Foundation. The authors wish to recognize and acknowledge the very significant cultural role and reverence that the summit of Mauna Kea has always had within the indigenous Hawaiian community.
