超大质量黑洞（SMBH）双星在星系合并期间和之后的形成和演化是我们在宇宙学背景下理解星系形成和演化的重要组成部分，例如用于预测宇宙星星形成历史或SMBH人口统计（预测发射引力波的事件）。如果星系在演化过程中合并，应该有许多双黑洞甚至多个黑洞，或者我们必须找出星系核中黑洞的多个发生了什么，例如它们是否足够接近合并导致引力波的发射，或者它们是否在引力弹弓相互作用中相互排斥。
The formation and evolution of supermassive black hole (SMBH) binaries during and after galaxy mergers is an important ingredient for our understanding of galaxy formation and evolution in a cosmological context, e.g. for predictions of cosmic star formation histories or of SMBH demographics (to predict events that emit gravitational waves). If galaxies merge in the course of their evolution, there should be either many binary or even multiple black holes, or we have to find out what happens to black hole multiples in galactic nuclei, e.g. whether they come sufficiently close to merge resulting from emission of gravitational waves, or whether they eject each other in gravitational slingshot interactions.
