cds-question@unistra.fractive-galactic-nucleivisible-astronomyspectroscopyblack-holesredshiftedseyfert-galaxiesWe report the results of reverberation mapping of three bright Seyfert galaxies, Mrk 79, NGC 3227, and Mrk 841, from a campaign conducted from 2016 December to 2017 May with the Wyoming Infrared Observatory (WIRO) 2.3m telescope. All three of these targets have shown asymmetric broad H{beta} emission lines in the past, although their emission lines were relatively symmetric during our observations. We measured H{beta} time lags for all three targets and estimated masses of their black holes-for the first time in the case of Mrk 841. For Mrk 79 and NGC 3227, the data are of sufficient quality to resolve distinct time lags as a function of velocity and to compute two-dimensional velocity-delay maps. Mrk 79 shows smaller time lags for high-velocity gas, but the distribution is not symmetric, and its complex velocity-delay map could result from the combination of both inflowing and outflowing H{beta} emitting disks that may be part of a single larger structure. NGC 3227 shows the largest time lags for blueshifted gas, and the two-dimensional velocity-delay map suggests a disk with some inflow. We compare our results with previous work and find evidence for different time lags despite similar luminosities, as well as evolving broad-line region structures.2020ApJ...905...77Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/905/77CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/126/331 : Spectrophotometry of nearby field galaxies (Jansen+ 2000)J/ApJ/613/682 : AGN central masses & broad-line regions (Peterson+, 2004)J/MNRAS/426/416 : Mrk 6 H{alpha}, H{beta} and H{gamma} sp.
