论文摘要
使用最新的高分辨率完全GPU N体模拟，我们首次证明了富含暗物质的卫星的插座自然解释了当前的黑洞被M31中的sub-parsec所抵消。潮汐特征的观察数据对我们模拟的初始条件提供了严格的约束。卫星通过动态摩擦加热M31的中央区域需要在第一次上述通道后的一个明显的黑洞抵消。达到最大偏移后，由于动态摩擦而导致的大型黑洞朝M31中心下沉，并确定它被观测值得出的亚比索所抵消。
Using state-of-the-art high-resolution fully GPU N-body simulations, we demonstrate for the first time that the infall of a dark matter rich satellite naturally explains a present black hole offset by sub-parsecs in M31. Observational data of the tidal features provide stringent constraints on the initial conditions of our simulations. The heating of the central region of M31 by the satellite via dynamical friction entails a significant black hole offset after the first pericentric passage. After having reached its maximum offset, the massive black hole sinks towards the M31 centre due to dynamical friction and it is determined to be offset by sub-parsecs as derived by observations.
