BL Lac天体的去束光度、同步峰频率和黑洞质量
The debeamed luminosity, sychrotron peak frequency and black hole mass of BL Lac objects
摘要：
我们估计的内禀光度和同步辐射峰值频率的多普勒因子的170 BL Lac对象的样本，其中的同步辐射峰值频率是通过拟合所收集的多波段数据从文献中构建的SED。我们发现，debamed无线电和光学核心光度遵循相同的相关性，发现FR I射电星系，这是在支持统一的BL Lac对象和FR I星系的基础上的方向。对于同步辐射峰值频率处的去束光亮度，我们发现亮度与同步辐射峰值频率之间存在显著的正相关关系。这意味着更强大的源可能在更高的频率下具有大部分喷流发射。在同步辐射峰值频率下，内禀光度与黑洞质量呈现较强的正相关性，而喷流功率的相关性较弱，说明更强的源可能有更重的黑洞。
英文摘要：
We estimate the intrinsic luminosities and synchrotron peak frequency using the derived Doppler factor for a sample of 170 BL Lac objects, of which the synchrotron peak frequency are derived by fitting the SED constructed with the collected multi-band data from literatures. We find that the debeamed radio and optical core luminosities follow the same correlation found for FR I radio galaxies, which is in support of the unification of the BL Lac objects and the FR I galaxies based on orientation. For the debeamed luminosity at synchrotron peak frequency, we find a significant positive correlation between the luminosity and intrinsic synchrotron peak frequency. This implies that the more powerful sources may have the majority of jet emission at higher frequency. At synchrotron peak frequency, the intrinsic luminosity and black hole mass show strong positive correlation, while mild correlation is found in the case of jet power, indicating that the more powerful sources may have heavier black hole.
