Abstract:
We developed a spectroscopic monitoring project to investigate the
kinematics of the broad-line region (BLR) in active galactic nuclei
(AGNs) with ultrafast outflows (UFOs). Mrk 79 is a radio-quiet AGN
with UFOs and warm absorbers and has been monitored by three
reverberation mapping (RM) campaigns, but its BLR kinematics are not
yet understood. In this paper, we report the results from a new RM
campaign of Mrk 79, which was undertaken with the Lijiang 2.4m
telescope. Mrk 79 appears to come out the faint state, with the mean
flux approximately a magnitude fainter than the historical record. We
successfully measured the lags of the broad emission lines including
Hβλ4861, Hγλ4340, HeIIλ4686, and
HeIλ5876 with respect to the varying AGN continuum. Based on
the broad Hβλ4861 line, we measured a black hole mass of
M•=5.13-1.55+1.57x107M☉, and an estimated
accretion rate of dM/dt•=(0.05±0.02)LEddc-2, indicating
that Mrk 79 is a sub-Eddington accretor. We found that Mrk 79 deviates
from the canonical Radius-Luminosity relationship. The marginal
blueshift of the broad HeIIλ4686 line detected from the rms
spectrum indicates outflow of high- ionization gas. The
velocity-resolved lag profiles of the broad Hγλ4340,
Hβλ4861, and HeIλ5876 lines show similar signatures
such that the largest lag occurs in the red wing of the lines and then
the lag decreases to both sides. These signatures may suggest that the
BLR of Keplerian motion probably exists as outflow gas motion. All
findings including UFOs, warm absorbers, and the kinematics of high-
and low-ionization BLR, may provide indirect evidence that the BLR of
Mrk 79 probably originates from a disk wind.
Description:
The spectroscopic and photometric observations of Mrk 79 were taken
using the Yunnan Faint Object Spectrograph and Camera (YFOSC) mounted
on the Lijiang 2.4m telescope (LJT).
The spectral monitoring of Mrk 79 started on 2017 November 1, and
terminated on 2018 March 13. We used Grism 14, which provides a
resolution of 92Å/mm (1.8Å/pixel) and covers the wavelength
range 3600-7460Å. In total, we obtained 72 spectroscopic
observations, spanning an observation period of 132 days.
The photometric images with the field of 10"x10" were obtained using a
Johnson V filter. In total, we obtained 62 photometric observations.
