Accretion of Galaxies around Supermassive Black Holes and a Theoretical Model of the Tully-Fisher and M-Sigma Relations

Nick Gorkavyi

AI总结:

本研究基于超大质量黑洞周围的星系吸积模型,解释了Tully-Fisher定律、Faber-Jackson定律及M-σ关系,并提出椭圆星系与盘星系的起源差异或与3D、2D吸积模式相关。

摘要:

我们在超大质量黑洞(SMBH)周围的星系吸积模型框架内,解释了观测到的、星系重子质量与星系边缘恒星运动速度之间的Tully-Fisher定律和Faber-Jackson定律。该吸积模型还可以解释超大质量黑洞质量与核球内恒星速度之间的M-σ关系。低角动量椭圆星系与高角动量盘星系的起源机制差异,可能与3D和2D吸积有关。

英文摘要:

The observed Tully-Fisher and Faber-Jackson laws between the baryonic mass of galaxies and the velocity of motion of stars at the edge of galaxies are explained within the framework of the model of accretion of galaxies around supermassive black holes (SMBH). The accretion model can also explain the M-sigma relation between the mass of a supermassive black hole and the velocity of stars in the bulge. The difference in the mechanisms of origin of elliptical galaxies with low angular momentum and disk galaxies with high angular momentum can be associated with 3D and 2D accretion.
