Query: The Lick AGN Monitoring Project 2016: Velocity-Resolved H{\beta} Lags in
  Luminous Seyfert Galaxies   We carried out spectroscopic monitoring of 21 low-redshift Seyfert 1 galaxies
using the Kast double spectrograph on the 3-m Shane telescope at Lick
Observatory from April 2016 to May 2017. Targeting active galactic nuclei (AGN)
with luminosities of {\lambda}L{\lambda} (5100 {\AA}) = 10^44 erg/s and
predicted H{\beta} lags of 20-30 days or black hole masses of 10^7-10^8.5 Msun,
our campaign probes luminosity-dependent trends in broad-line region (BLR)
structure and dynamics as well as to improve calibrations for single-epoch
estimates of quasar black hole masses. Here we present the first results from
the campaign, including H{\beta} emission-line light curves, integrated
H{\beta} lag times (8-30 days) measured against V-band continuum light curves,
velocity-resolved reverberation lags, line widths of the broad H{\beta}
components, and virial black hole mass estimates (10^7.1-10^8.1 Msun). Our
results add significantly to the number of existing velocity-resolved lag
measurements and reveal a diversity of BLR gas kinematics at moderately high
AGN luminosities. AGN continuum luminosity appears not to be correlated with
the type of kinematics that its BLR gas may exhibit. Follow-up direct modeling
of this dataset will elucidate the detailed kinematics and provide robust
dynamical black hole masses for several objects in this sample.
