TL;DR: In this paper, a 64-night spectroscopic monitoring campaign at the Lick Observatory 3m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0: 05) Seyfert 1 galaxies with expected masses in the range of 10 6 -10 7, and also the well-studied nearby active galactic nucleus (AGN) NGC 5548.

TL;DR: In this article, a 64-night spectroscopic monitoring campaign at the Lick Observatory 3m Shane telescope with the aim of measuring the masses of the black holes in 12 nearby (z < 0.05) Seyfert 1 galaxies with expected masses in the range ~10^6-10^7 M_sun and also the well-studied nearby active galactic nucleus (AGN) NGC 5548.
Journal ArticleDOI
The M87 Black Hole Mass From Gas-Dynamical Models Of Space Telescope Imaging Spectrograph Observations
TL;DR: In this paper, the authors apply comprehensive gas-dynamical models that include the propagation of emission-line profiles through the telescope and spectrograph optics to new Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope, and find that a small amount of velocity dispersion internal to the gas disk is required to match the observed line widths.

The Lick AGN Monitoring Project: The M BH-σ* Relation for Reverberation-mapped Active Galaxies
Jong-Hak Woo,Jong-Hak Woo,Tommaso Treu,Tommaso Treu,Aaron J. Barth,Shelley A. Wright,Jonelle L. Walsh,Misty C. Bentz,Paul Martini,Vardha N. Bennert,Gabriela Canalizo,Alexei V. Filippenko,Elinor L. Gates,Jenny E. Greene,Weidong Li,Matthew A. Malkan,Daniel Stern,Takeo Minezaki +17 more
TL;DR: In this paper, the authors measured the velocity dispersions of a sample of local Seyfert 1 galaxies, for which they have recently determined black hole masses using reverberation mapping, and derived an updated value of the virial coefficient f by finding the value which places the reverberation masses in best agreement with the MBH-σ* relation of quiescent galaxies.
