超大質(zhì)量雙黑洞系統(tǒng)中的吸積盤-formationand(專業(yè)版)
【正文】 現(xiàn)有的觀測表明， FRII射電星系中的吸積盤是標準的而 FRI射電星系中的吸積盤則很可能是非標準的?觀測 ： 噴流遺跡與寄住星系盤垂直?理論 ：在吸積盤與超大質(zhì)量雙黑洞發(fā)生相互作用前，吸積盤因角動量守恒而與星系盤共面，因而產(chǎn)生的噴流與吸積盤和星系盤垂直?觀測 ： 活動的噴流隨機取向?理論 ：新噴流方向垂直于雙黑洞軌道面，而星系并合形成的超大質(zhì)量雙黑洞相對于星系盤取向隨機VLA”HST”156 radio sourcesRandom distribution of jet orientations(Liu, Zhang, Wu, 2023, in preparation)Random ()With respect to major axis of host galaxyWith respect to dust lane in host galaxyΦ: angle between dust lane and major axis of host galaxyRelaxed systemUnrelaxed system Coplanar binarydisk system: resonant interactionn The potential due to the secondaryrrsFourier expensionΚ :epicyclic frequency?Secondary perturbation: initiates density waves at Lindlad resonance radiusm=The whole inner region is destroyed by wavesn Opens a gap in the accretion diskn The outer boundary of the gap:n The inner boundary:Lin Papaloizou, 1986, ApJr=R/R0。 rs=、 Removal of matter in the inner accretion disk (Liu, Wu, Cao, 2023, MNRAS)Binarydisk resonant interactionDisk truncation due to SMBBHs coalescence?
