$M_{\bullet}$与PDMATHAAB关系与$M_{\bullet}$与$σ$关系的最新比较及星系质量问题

An updated comparison of the $M_{\bullet}$ vs $M_{G}σ^2$ relation with $M_{\bullet}$ vs $σ$ and the problem of the masses of galaxies

A. L. Iannella, A. Feoli

摘要:

我们在一系列的论文中研究了$M_{\bullet}$与$M_{G}σ^2$关系的性质,发现用HR图描述恒星的演化和预测用其它标度关系难以猜测的超大质量黑洞的质量是有用的。本文通过对五个星系样本的分析,发现该关系具有类似于$M_{\bullet} - σ$的内禀散射,但比$M_{\bullet} - σ$更好地遵循理论模型。此外,我们分析的作用,在$M_{\bullet}$与$M_{G}σ^2$关系的行为,因为与$M_{\bullet} - σ$的差异往往是由正确的银河系质量的样本的选择。

英文摘要:

We have studied, in a series of papers, the properties of the $M_{\bullet}$ versus $M_{G}σ^2$ relation and we have found that it is useful to describe the evolution of galaxies in the same way as the HR diagram does for stars and to predict the masses of Supermassive Black Holes that are difficult to be guessed using other scaling relations. In this paper, analyzing five samples of galaxies, we find that this relation has intrinsic scatter similar to the $M_{\bullet} - σ$, but follows the theoretical models much better than the $M_{\bullet} - σ$. Furthermore, we analyze the role of the bulge mass in the behavior of $M_{\bullet}$ versus $M_{G}σ^2$ relation because the difference with the $M_{\bullet} - σ$ is often determined by the choice of the right sample of galactic masses.
