【摘要】：喷流的形成与黑洞质量及黑洞自旋之间存在着很大关系.讨论黑洞质量及黑洞自旋与喷流能量的关系对喷流形成及结构的研究有着重要的意义.从文献资料中收集了65个射电类星体源.这些源包含了35个陡谱射电类星体(SSRQs),30个平谱射电类星体(FSRQs).通过样本数据研究黑洞质量及黑洞自旋与喷流能量的相关性.研究结果表明:(1)65个射电类星体的黑洞质量与喷流能量存在明显的相关性,这与Zensus所得出的结论相同;(2)65个射电类星体的黑洞自旋与喷流能量存在相关性.尤其在爱丁顿磁场条件下(B=BEDD),黑洞自旋与喷流能量的相关性最为明显,其相关系数要比黑洞质量与喷流能量的相关系数高;(3)陡谱射电类星体与平谱射电类星体的自旋数据分布存在一定差异;(4)研究结果进一步证明了喷流能量不仅与黑洞质量有关,同时也很可能与黑洞的自旋能量存在关系.黑洞喷流的形成很可能是黑洞质量与黑洞自旋共同作用的结果.这些研究结果与其他方法获得的结果是一致的.
[Abstract]:The formation of the jet is closely related to the mass of the black hole and the spin of the black hole. It is of great significance to study the formation and structure of the jet flow by discussing the relationship between the mass of the black hole and the spin-energy of the black hole. 65 radio quasar sources were collected from literature. These sources contain 35 steep-spectrum radio quasars (SSRQs), 30 flat spectrum radio quasars (FSRQs). The correlation between the black hole mass and the spin-energy of the black hole is studied by the sample data. The results show that: (1) the black hole mass of 65 radio quasars is significantly correlated with the jet energy, which is the same as that of Zensus, and (2) the black hole spin and jet energy of 65 radio quasars are correlated. Especially in the Eddington magnetic field (B=BEDD), the correlation between the spins and the jet energy of the black hole is most obvious, and the correlation coefficient is higher than the correlation coefficient between the mass and the jet energy of the black hole. (3) the distribution of spin data between steep-spectrum radio quasars and flat spectrum radio quasars is different. (4) the results further prove that the jet energy is not only related to the mass of the black hole, but also possibly related to the spin energy of the black hole. The formation of black hole jet is probably the result of the interaction between black hole mass and black hole spin. These results are consistent with those obtained by other methods.
