Description

Circumbinary disks are expected to exist around supermassive
black-hole binaries as a consequence of accretion from the
interstellar medium following galaxy mergers. I will discuss recent
works on numerical modeling of circumbinary accretion, focusing
short-term and long-term variabilities, and angular momentum transfer
between the disk and the binary -- the result suggests that the
long-standing notion of binary orbital decay driven by circumbinary
disk may not always hold. I will also discuss the dynamics of stellar-mass
black-hole binaries embedded in AGN disks.
