SMBH质量与M_G σ ^2关系:真实数据与数值模型的比较

The SMBH mass versus M_G sigma^2 relation: A comparison between real data and numerical models

A. Feoli, L. Mancini, F. Marulli, S. van den Bergh

摘要:

位于宿主星系中心的超大质量黑洞的质量与相应的凸起随机运动的动能之间的关系可以重新解释为星系的年龄-温度图。该关系式比M_bh-M_G、M_bh-L_G和M_bh-sigma定律更符合实验数据。使用从不同星系目录中提取的三个样本证实了这一说法的有效性。在LambdaCDM宇宙学的框架下,我们的关系已经与基于千禧年模拟的两个星系形成模型的预测进行了比较。

英文摘要:

The relation between the mass of supermassive black holes located in the center of the host galaxies and the kinetic energy of random motions of the corresponding bulges can be reinterpreted as an age-temperature diagram for galaxies. This relation fits the experimental data better than the M_bh-M_G, M_bh-L_G, and M_bh-sigma laws. The validity of this statement has been confirmed by using three samples extracted from different catalogues of galaxies. In the framework of the LambdaCDM cosmology our relation has been compared with the predictions of two galaxy formation models based on the Millennium Simulation.
