cds-question@unistra.frseyfert-galaxiesvisible-astronomybroad-band-photometryspectroscopyWe 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 H{beta}{lambda}4861, H{gamma}{lambda}4340, HeII{lambda}4686, and HeI{lambda}5876 with respect to the varying AGN continuum. Based on the broad H{beta}{lambda}4861 line, we measured a black hole mass of M_{bullet}_=5.13_-1.55_^+1.57^x10^7^M_{sun}_, and an estimated accretion rate of dM/dt_{bullet}_=(0.05+/-0.02)L_Edd_c^-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 HeII{lambda}4686 line detected from the rms spectrum indicates outflow of high- ionization gas. The velocity-resolved lag profiles of the broad H{gamma}{lambda}4340, H{beta}{lambda}4861, and HeI{lambda}5876 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.2019ApJ...887..135Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/887/135CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/ApJ/510/659 : Size and Structure of AGN in NGC 5548 (Peterson+, 1999)J/ApJ/549/155 : [OIII] emission in a sample of AGNs (Nagao+, 2001)J/ApJS/146/1 : O VI absorption in FUSE survey (Wakker+, 2003)J/ApJS/146/125 : O VI in the galactic halo (Savage+, 2003)J/ApJ/613/682 : AGN masses & broad-line region sizes (Peterson+, 2004)J/ApJ/622/129 : Lag-luminosity relationship in AGN (Sergeev+, 2005)J/ApJ/641/L21 : BH mass and velocity dispersion relation (Greene+, 2006)J/A+A/473/369 : VISIR/VLT MIR imaging of Seyfert nuclei (Haas+, 2007)J/ApJ/658/815 : Radio loudness of active galactic nuclei (Sikora+, 2007)J/ApJ/660/1072 : Unified model of active galactic nuclei (Wang+, 2007)J/ApJ/661/L143 : Star formation rate in Seyfert galaxies (Wang+, 2007)J/other/ChA+A/32.351 : Accretion rate distributions of AGNs (Bao+, 2008)J/MNRAS/383/581 : Broad-line Balmer decrements in blue AGN (Dong+, 2008)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)J/ApJ/702/1353 : H{beta} and V-band light curves of NGC 4051 (Denney+, 2009)J/ApJ/697/182 : Dust emission from unobscured AGN (Thompson+, 2009)J/ApJ/702/767 : CIV and FeK{alpha} Baldwin effects in AGNs (Wu+, 2009)J/ApJ/705/14 : Seyfert galaxies in the mid-IR (Deo+, 2009)J/MNRAS/407/2399 : AGN activity and black hole mass (McKernan+, 2010)J/ApJ/709/1257 : Spitzer-IRS spectra of Seyfert.
