cds-question@unistra.fractive-galactic-nucleivisible-astronomyspectroscopyredshiftedWe have started a long-term reverberation mapping (RM) project using the Wyoming Infrared Observatory 2.3m telescope titled "Monitoring AGNs with H{beta} Asymmetry" (MAHA). The motivations of the project are to explore the geometry and kinematics of the gas responsible for complex H{beta} emission-line profiles, ideally leading to an understanding of the structures and origins of the broad-line region (BLR). Furthermore, such a project provides the opportunity to search for evidence of close binary supermassive black holes. We describe MAHA and report initial results from our first campaign, from 2016 December to 2017 May, highlighting velocity-resolved time lags for four active galactic nuclei (AGNs) with asymmetric H{beta} lines. We find that 3C120, Ark120, and Mrk6 display complex features different from the simple signatures expected for pure outflow, inflow, or a Keplerian disk. While three of the objects have been previously reverberation mapped, including velocity-resolved time lags in the cases of 3C120 and Mrk6, we report a time lag and corresponding black hole mass measurement for SBS1518+593 for the first time. Furthermore, SBS1518+593, the least asymmetric of the four, does show velocity-resolved time lags characteristic of a Keplerian disk or virialized motion more generally. Also, the velocity-resolved time lags of 3C120 have significantly changed since previously observed, indicating an evolution of its BLR structure. Future analyses of the data for these objects and others in MAHA will explore the full diversity of H{beta} lines and the physics of AGN BLRs.2018ApJ...869..142Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/869/142CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/260 : The SDSS-DR7 quasar catalog (Schneider+, 2010)J/ApJS/145/199 : Optical spectroscopic atlas low-redshift AGN (Marziani+,2003)J/A+A/422/925 : Profile variability in lines of NGC 5548 (Shapovalova+ 2004)J/ApJ/613/682 : AGN central masses & broad-line region sizes (Peterson+,2004)J/ApJ/687/78 : FeII emission in quasars (Hu+, 2008)J/ApJ/683/L115 : Intermediate-line region in quasars (Hu+, 2008)J/ApJ/705/L76 : AGNs with double-peaked [OIII] lines (Wang+, 2009)J/ApJ/716/993 : LAMP: reverberation mapping of H and He lines (Bentz+, 2010)J/ApJ/732/121 : V-band and H{beta} monitoring of Z299-15 (Barth+, 2011)J/ApJS/194/45 : QSO properties from SDSS-DR7 (Shen+, 2011)J/MNRAS/426/416 : Mrk 6 H{alpha}, H{beta} & H{gamma} spectra (Doroshenko+,2012)J/ApJS/201/23 : Spectroscopy of 88 z<0.7 SDSS QSOs (Eracleous+, 2012)J/ApJ/755/60 : Reverberation mapping for 5 Seyfert 1 galaxies (Grier+, 2012)J/ApJ/779/109 : Long-term monitoring of NGC 5548 (Peterson+, 2013)J/MNRAS/431/836 : Type 1 AGN at low z.
