论文摘要
我们在九个不同的频率（从红外到超紫罗莱氏光子光子能量）中，将新颖和极度发光的瞬态ASASSN-15LH的光曲线作为在潮汐破坏事件发生后产生的不断发展的相对盘。当$ m _ {\ rm acc} \ simeq 0.07 m _ {\ odot} $同时获得所有九个光曲线的良好曲线，并获得质量$ m \ simeq 10^9 m _ {\ odot} $的黑色孔，并接近最大的$ a/r _ $ a/r _ = 0.99 $。最适合的黑洞质量与银河缩放关系中的许多现有估计值一致。如果得到证实，我们的结果代表了迄今为止最庞大的迅速旋转黑洞之一的检测，并且是ASASSN-15LH的TDE起源的有力证据。这将是在光学和红外频率下以圆盘状态观察到的第一个TDE。
We model the light curves of the novel and extremely luminous transient ASASSN-15lh at nine different frequencies, from infrared to ultra-violet photon energies, as an evolving relativistic disc produced in the aftermath of a tidal disruption event. Good fits to all nine light curves are simultaneously obtained when $M_{\rm acc} \simeq 0.07 M_{\odot}$ is accreted onto a black hole of mass $M \simeq 10^9 M_{\odot}$, and near maximal rotation $a/r_g = 0.99$. The best fit black hole mass is consistent with a number of existing estimates from galactic scaling relationships. If confirmed, our results represent the detection of one of the most massive rapidly spinning black holes to date, and are strong evidence for a TDE origin for ASASSN-15lh. This would be the first TDE to be observed in the disc dominated state at optical and infrared frequencies.
