We present the final results from a high sampling rate, multi-month, spectrophotometric reverberation mapping campaign undertaken to obtain either new or improved Hbeta reverberation lag measurements for several relatively low-luminosity AGNs. We have reliably measured thetime delay between variations in the continuum and Hbeta emission line in six local Seyfert 1 galaxies. These measurements are used to calculate the mass of the supermassive black hole at the center of each of these AGNs. We place our results in context to the most current calibration of the broad-line region (BLR) R-L relationship, where our results remove outliers and reduce the scatter at the low-luminosity end of this relationship. We also present velocity-resolved Hbeta time delay measurements for our complete sample, though the clearest velocity-resolved kinematic signatures have already been published.
Mass of the black hole in the Seyfert 1.5 galaxy H 0507+164 from reverberation mapping
我们提出了我们的X射线源H 0507+164，一个低光度塞弗特1.5星系在红移z = 0.018的光学监测活动的结果。光谱观测在2007年11月21日至12月26日的22个夜晚进行。在同一时期还获得了13个夜晚的R波段光度观测。在我们的监测期间，发现银河系的连续谱和宽线通量发生了变化。R波段相对于伴星的微分光变曲线也显示出类似的变化。使用互相关分析，我们估计的时间延迟为3.01天（在休息帧），在5100埃的光学连续谱中的变化的宽H-β线通量的响应。利用这个时间延迟和H β谱线的宽度，我们估计宽线区（BLR）的半径为2.53 x 10^{-3}秒差距，黑洞的质量为9.62 x 10^{6}太阳质量。
