We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

The next two decades are expected to open the door to the first coincident detections of
electromagnetic (EM) and gravitational-wave (GW) signatures associated with massive …

We present the to-date largest parameter space exploration of binaries in circumbinary discs
(CBDs), deriving orbital evolution prescriptions for eccentric, unequal mass binaries from our …

Circumbinary disks are found in a variety of astrophysical scenarios, spanning binary star
formation to accreting supermassive black hole binaries. Depending on the characteristics of …

We have investigated, both analytically and numerically, accreting supermassive black hole
binaries as they inspiral due to gravitational radiation to elucidate the decoupling of binaries …

Much of the parameter space relevant to the evolution of astrophysical circumbinary
accretion discs remains unexplored. We have carried out a suite of circumbinary disc …

Modern numerical hydrodynamics tools have recently enabled detailed examinations of
binaries accreting from prograde circumbinary discs. These have reframed the current …

We present a suite of high-resolution hydrodynamic simulations of binaries immersed in
circumbinary accretion discs (CBDs). For the first time, we investigate the preferential …

ABSTRACT The upcoming Laser Interferometer Space Antenna (LISA) is expected to detect
gravitational waves (GWs) from massive black hole binaries (MBHB). Finding the …

We show that gas disks around the components of an orbiting binary system (so-called
minidisks) may be susceptible to a resonant instability that causes the minidisks to become …
