Monitoring AGNs with H${\hat{I}}^2$ Asymmetry. IV. First Reverberation Mapping Results of 14 AGNs

Abstract

We report first-time reverberation mapping results for 14 AGNs from the ongoing Monitoring AGNs with H${\hat{I}}^2$ Asymmetry campaign (MAHA). These results utilize optical spectra obtained with the Long Slit Spectrograph on the Wyoming Infrared 2.3m Telescope between 2017 November-2023 May. MAHA combines long-duration monitoring with high cadence. We report results from multiple observing seasons for 9 of the 14 objects. These results include H${\hat{I}}^2$ time lags, supermassive black hole masses, and velocity-resolved time lags. The velocity-resolved lags allow us to investigate the kinematics of the broad-line region.
