REVERBERATION MAPPING RESULTS FOR FIVE SEYFERT 1 GALAXIES

We present the results from a detailed analysis of photometric and spectrophotometric data on five Seyfert 1 galaxies observed as a part of a recent reverberation mapping program. The data were collected at several observatories over a 140 day span beginning in 2010 August and ending in 2011 January. We obtained high sampling-rate light curves for Mrk 335, Mrk 1501, 3C 120, Mrk 6, and PG 2130+099, from which we have measured the time lag between variations in the 5100 Å continuum and the Hβ broad emission line. We then used these measurements to calculate the mass of the supermassive black hole at the center of each of these galaxies. Our new measurements substantially improve previous measurements of MBH and the size of the broad line-emitting region for four sources and add a measurement for one new object. Our new measurements are consistent with photoionization physics regulating the location of the broad line region in active galactic nuclei.

我们展示了对五个赛弗特1型星系的光度和分光光度数据进行详细分析的结果，这些星系是近期一个反响映射项目的观测对象。数据是在2010年8月至2011年1月的140天期间，由多个天文台收集的。我们获得了Mrk 335、Mrk 1501、3C 120、Mrk 6和PG 2130 + 099的高采样率光变曲线，由此我们测量了5100 Å连续谱的变化和Hβ宽发射线之间的时间延迟。然后我们利用这些测量结果计算了每个星系中心的超大质量黑洞的质量。我们的新测量结果极大地改进了之前对四个源的$M_{BH}$以及宽线发射区大小的测量，并增加了对一个新天体的测量。我们的新测量结果与光致电离物理调控活动星系核中宽线区位置的理论相符。
