我们提出了针对MGC-06-30-15的混响活动的结果。在2012年春季进行的四个月的分光光度监测和宽带光度监测，确定了活动星系核（AGN）静止框架中宽Hβ发射线的时间延迟τ = 5.3 ± 1.8天。结合发射谱线可变部分的宽度，我们确定黑洞质量为MBH =（1.6 ± 0.4）× 106 M ~（？）Hβ时延和黑洞质量与其它反射映射活动星系核的RBLR-L和MBH-σ σ关系的预期值吻合得很好。Hβ时间延迟与宽波段近红外延迟的关系也很好地吻合，其中宽波段区域的有效尺寸比尘埃环内缘小1.4 ~ 5倍。此外，混响为基础的质量是在良好的协议与估计的比例关系的突破，在X射线功率谱密度，并与约束的基础上恒星运动学来自积分场光谱的内部10.5千秒差距的星系。
We present the results of a reverberation campaign targeting MGC-06-30-15. Spectrophotometric monitoring and broad-band photometric monitoring over the course of four months in spring 2012 allowed a determination of a time delay in the broad Hβ emission line of τ = 5.3 ± 1.8 days in the rest frame of the active galactic nucleus (AGN). Combined with the width of the variable portion of the emission line, we determine a black hole mass of MBH = (1.6 ± 0.4) × 106 M⊙. Both the Hβ time delay and the black hole mass are in good agreement with expectations from the RBLR–L and MBH–σ⋆ relationships for other reverberation-mapped AGNs. The Hβ time delay is also in good agreement with the relationship between Hβ and broad-band near-IR delays, in which the effective size of the broad-line region is ∼4–5 times smaller than the inner edge of the dust torus. Additionally, the reverberation-based mass is in good agreement with estimates from the scaling relationship of the break in the X-ray power spectral density, and with constraints based on stellar kinematics derived from integral field spectroscopy of the inner ∼0.5 kpc of the galaxy.
