我们提出了五个活动星系核的速度分辨混响结果。我们使用最大熵法恢复了四个对象的速度延迟图：Mrk 335， Mrk 1501, 3C 120和PG 2130+099。对于第五个，Mrk 6，我们只能测量Hβ发射线不同速度箱的平均时间延迟。四个速度延迟映射显示了每个对象的唯一动态特征。对于3C 120， Balmer线显示的运动特征与倾斜盘和流入气体一致，但He ii λ4686发射线仅表明流入气体。Mrk 335、Mrk 1501和PG 2130+099的巴尔默谱线显示气体流入的迹象，但Mrk 335的He ii发射与倾斜盘一致。我们还从Mrk 6的速度分析中看到了病毒运动和气体流入的初步证据。3C 120和Mrk 335的地图是迄今为止定义最清晰的两张速度延迟地图。这些地图构成了我们已经解决速度延迟地图的物体数量的大量增加，并为基于反射的黑洞质量测量的可靠性提供了证据。
We present velocity-resolved reverberation results for five active galactic nuclei. We recovered velocity-delay maps using the maximum entropy method for four objects: Mrk 335, Mrk 1501, 3C 120, and PG 2130+099. For the fifth, Mrk 6, we were only able to measure mean time delays in different velocity bins of the Hβ emission line. The four velocity-delay maps show unique dynamical signatures for each object. For 3C 120, the Balmer lines show kinematic signatures consistent with both an inclined disk and infalling gas, but the He ii λ4686 emission line is suggestive only of inflow. The Balmer lines in Mrk 335, Mrk 1501, and PG 2130+099 show signs of infalling gas, but the He ii emission in Mrk 335 is consistent with an inclined disk. We also see tentative evidence of combined virial motion and infalling gas from the velocity-binned analysis of Mrk 6. The maps for 3C 120 and Mrk 335 are two of the most clearly defined velocity-delay maps to date. These maps constitute a large increase in the number of objects for which we have resolved velocity-delay maps and provide evidence supporting the reliability of reverberation-based black hole mass measurements.
