Abstract

We report first-time reverberation-mapping results for 14 active galactic nuclei (AGNs) from the ongoing Monitoring AGNs with Hβ Asymmetry campaign (MAHA). These results utilize optical spectra obtained with the Long Slit Spectrograph on the Wyoming Infrared 2.3 m Telescope between 2017 November and 2023 May. MAHA combines long-duration monitoring with high cadence. We report results from multiple observing seasons for nine of the 14 objects. These results include Hβ 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.

监测具有 Hβ 不对称的 AGN。IV.14 个活动星系核的首次混响绘图结果

我们首次报告了正在进行的Hβ不对称AGN监测活动（MAHA）中14个活动星系核（AGN）的混响绘图结果。这些结果利用的是 2017 年 11 月至 2023 年 5 月期间通过怀俄明红外 2.3 米望远镜上的长缝摄谱仪获得的光学光谱。MAHA 结合了长时间监测和高频率观测。我们报告了 14 个天体中 9 个天体在多个观测季节的观测结果。这些结果包括 Hβ 时滞、超大质量黑洞质量和速度分辨时滞。速度分辨时滞使我们能够研究宽线区的运动学。
