SMBH吸积和合并:消除对称性

SMBH accretion & mergers: removing the symmetries

Andrew King, Chris Nixon

摘要:

本文综述了近年来超大质量黑洞吸积流的研究进展。这在很大程度上消除了早期关于对称性和规律性的假设,例如对齐和交叉盘旋转。这就允许了更丰富的各种效应,通常是因为角动量的抵消允许了快速的下降。潜在的应用包括较低的SMBH自旋,允许更快的质量增长和抑制引力波反应反冲合并,气体辅助SMBH合并,以及星系中心的近动力学吸积。

英文摘要:

We review recent progress in studying accretion flows on to supermassive black holes (SMBH). Much of this removes earlier assumptions of symmetry and regularity, such as aligned and prograde disc rotation. This allows a much richer variety of effects, often because cancellation of angular momentum allows rapid infall. Potential applications include lower SMBH spins allowing faster mass growth and suppressing gravitational-wave reaction recoil in mergers, gas-assisted SMBH mergers, and near-dynamical accretion in galaxy centres.
