Abstract:
We present the first results from a reverberation-mapping campaign
undertaken during the first half of 2012, with additional data on one
active galactic nucleus (AGN) (NGC 3227) from a 2014 campaign. Our
main goals are (1) to determine the black hole masses from
continuum-Hβ reverberation signatures, and (2) to look for
velocity-dependent time delays that might be indicators of the gross
kinematics of the broad-line region. We successfully measure Hβ
time delays and black hole masses for five AGNs, four of which have
previous reverberation mass measurements. The values measured here are
in agreement with earlier estimates, though there is some intrinsic
scatter beyond the formal measurement errors. We observe
velocity-dependent Hβ lags in each case, and find that the
patterns have changed in the intervening five years for three AGNs
that were also observed in 2007.
Description:
The primary objective of this campaign is to determine the kinematics
and structure of the BLR in a few well-studied bright AGNs. In
particular, we are re-examining NGC 3227, NGC 3516, and NGC 5548 from
Denney+ (2009ApJ...704L..80D 2009ApJ...704L..80D). We also included in our observing
program NGC 4151, for which the best reverberation data are from a
weather-abbreviated campaign in 2005 (Bentz+ 2006ApJ...651..775B 2006ApJ...651..775B).
Sources included in the 2012 campaign were Mrk 374, Mrk 382, Mrk 478,
Mrk 618, and Mrk 704.
The principal data source for both the 2012 and 2014 campaigns was the
Boller and Chivens CCD spectrograph on the MDM Observatory 1.3m
McGraw-Hill telescope on Kitt Peak. The 2012 campaign ran from the
beginning of 2012 January through the end of 2012 April. The spectral
coverage is over the range 4400-5850Å and the resolution is 7.9Å.
The 2012 campaign also included spectroscopic observations obtained at
the Asiago Astrophysical Observatory of Padova University with the
1.22m Galileo telescope and the Cassegrain Boller & Chivens
spectrograph. The spectral coverage is over the range 3200-8000Å
and the resolution is 10.5Å.
The Crimean Astrophysical Observatory (CrAO) provided spectra from the
Nasmith spectrograph and SPEC-10 CCD on the 2.6m Shajn telescope. It
covered wavelengths from 3900 to 6100Å.
Finally, the 2.3m telescope at Wyoming Infrared Observatory (WIRO) and
the WIRO Long Slit Spectrograph contributed a small number of
observations. A spectral coverage between 4400 and 5600Å was used.
We supplemented our spectroscopic continuum light curves with
photometric observations. Observations in 2012 were obtained with the
0.5m Centurian 18 at Wise Observatory (WC18) and with the 0.9m at West
Mountain Observatory (WMO).
We also used data from the All-Sky Automated Survey for SuperNovae
(ASAS-SN, Shappee+ 2014, J/ApJ/788/48). These data are from the first
unit of ASAS-SN, Brutus, which consisted in 2012 of two 14cm aperture
Nikon telephoto lenses on a single mount in the Faulkes Telescope
North enclosure on Mount Haleakala, Hawaii.
In addition, the 2014 campaign included imaging from CrAO,
Fountainwood Observatory (FWO), and the Las Cumbres Observatory (LCO).
The CrAO images were from the 0.7m telescope; observations from FWO
were obtained with a 0.4m telescope. The LCO data were obtained using
their worldwide network of 1m telescopes in the Sloan ugriz bands.
When needed, we adopt a cosmological model with Ωm=0.30,
ΩΛ=0.70, and H0=70km/s/Mpc.

Note (1): The luminosity distance in a consensus cosmology, except for NGC3227
which is interacting with an elliptical companion, NGC3226, which has
a surface-brightness fluctuation distance of 23.5Mpc (Tonry+
2001ApJ...546..681T 2001ApJ...546..681T). We therefore adopt this as the distance to NGC3227.
In the case of NGC4151, we use the distance of 13.9Mpc adopted by
Onken+ (2014ApJ...791...37O 2014ApJ...791...37O).
See section 2.1 for further details.
Note (2): Observed luminosity (corrected for Galactic extinction), calculated
from the observed 5100Å rest-frame light curve.
