论文摘要
我们说明了黑洞二进制文件的新颖签名，它们对它们环境中水层发射运动学的影响。在模拟的帮助下，我们根据校准了已知的Maser Galaxy NGC 4258的相干长度来确定团块对MASE进行MASE的条件。然后使用该条件来识别二进制黑孔系统周围的MASING团块，并量化相对于单个黑洞的运动学和光谱差异。在某些普通情况下，发现在二进制黑洞周围的蓝色变速层优先遵循单个黑洞箱中观察到的开普勒旋转曲线。然而，发现红移的偏移与这种关系明显偏离，并且显示出更大的散射，并且倾向于沿视路线降低速度的绝对值较低。 MASERS的光谱与视线速度的关系也显示了双峰结构，让人联想到最近对MRK 1等系统的观察结果。我们的结果激励了未来的前景，可以在水层发射的帮助下识别二进制黑洞候选。
We illustrate a novel signature of black hole binaries from their effect on the kinematics of water maser emission in their environments. With the help of simulations, we establish the condition for clumps to mase based on their coherence lengths calibrated to those of the known maser galaxy NGC 4258. This is then used to identify masing clumps around a binary black hole system, and quantify the kinematic and spectral differences relative to the single black hole case. For some generic circumstances, blue-shifted masers around a binary black hole are found to preferentially follow the Keplerian rotation curve observed in the single black hole case. The redshifted ones, however, are found to visibly deviate from this relation, and also display more scatter with a tendency towards lower absolute values of the velocity along the line-of-sight. The spectrum of the masers as a function of line-of-sight velocity also shows a double peaked structure, reminiscent of recent observations of systems such as Mrk 1. Our results motivate future prospects for identifying binary black hole candidates with the help of water maser emissions.
