The effect of AGN feedback on the migration time-scale of supermassive black holes binaries
Monthly Notices of the Royal Astronomical Society（2018）
摘要
The gravitational interaction at parsec to sub-parsec scales between a circumbinary gas disc and a super massive black hole binary (SMBHB) is a promising mechanism to drive the migration of SMBHBs towards coalescence. The typical dynamical evolution can be separated in two main regimes: (I) slow migration (T mig ∼ 103 − 4 × Torb), where viscous torques are not efficient enough to redistribute the ...
