摘要:

对塞弗特1号星系NGC 7469进行的一项大型混响映射研究得出了β 4861和He II 4686的发射线滞后,以及大约1000万太阳质量的中心黑洞质量测量结果,与以前的测量结果一致。在监测活动期间,非常低的可变性使我们无法实现从数据中恢复速度延迟图的最初目标,但随着新的Hbeta测量,NGC 7469不再是发射Hbeta的宽线区域的大小与AGN光度之间关系的异常值。有必要降低连续谱和Hbeta和He II 4686线光变曲线以及不同时间序列分析方法的存档UV数据的趋势,以获得一致的结果。

英文摘要:

A large reverberation mapping study of the Seyfert 1 galaxy NGC 7469 has yielded emission-line lags for Hbeta 4861 and He II 4686 and a central black hole mass measurement of about 10 million solar masses, consistent with previous measurements. A very low level of variability during the monitoring campaign precluded meeting our original goal of recovering velocity-delay maps from the data, but with the new Hbeta measurement, NGC 7469 is no longer an outlier in the relationship between the size of the Hbeta-emitting broad-line region and the AGN luminosity. It was necessary to detrend the continuum and Hbeta and He II 4686 line light curves and those from archival UV data for different time-series analysis methods to yield consistent results.
