Abstract The Laser Interferometer Space Antenna (LISA) will be a transformative experiment
for gravitational wave astronomy, and, as such, it will offer unique opportunities to address …

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 quest for binary and dual supermassive black holes (SMBHs) at the dawn of the multi-
messenger era is compelling. Detecting dual active galactic nuclei (AGN)–active SMBHs at …

Using numerical hydrodynamics calculations and a novel method for densely sampling
parameter space, we measure the accretion and torque on a binary system from a …

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 …

Supermassive black hole binaries (SMBHBs) at sub-parsec separations should be common
in galactic nuclei, as a result of frequent galaxy mergers. Hydrodynamical simulations of …

We solve the equations of two-dimensional hydrodynamics describing a circumbinary disk
accreting onto an eccentric, equal-mass binary. We compute the time rate of change of the …

Numerical studies of gas accretion onto supermassive black hole binaries have generally
been limited to conditions where the circumbinary disk (CBD) is 10–100 times thicker than …

We present 3D hydrodynamical models of the HD 142527 protoplanetary disc, a bright and
well-studied disc that shows spirals and shadows in scattered light around a 100 au gas …

We carry out 2D viscous hydrodynamics simulations of circumbinary disk (CBD) accretion
using AREPO. We resolve the accretion flow from a large-scale CBD down to the streamers …
