Decoupling of a supermassive black hole binary from its magnetically arrested circumbinary accretion disk

Merging supermassive black hole (SMBH) binaries will likely be surrounded by a circumbinary accretion disk. Close to merger, gravitational radiation-driven inspiral will happen on timescales faster than the effective viscous time at the disk cavity w

Magnetically Arrested Circumbinary Accretion Flows

Autor: Most, Elias R., Wang, Hai-Yang

Publikováno v: ApJL 973 L19 (2024)

Binary systems with comparable masses and a surrounding accretion disk can accrete gas through spiral accretion streams penetrating the central cavity formed by tidal interactions. Using three-dimensional Newtonian magnetohydrodynamics simulations, w

Hydrodynamical Simulations of Circumbinary Accretion: Balance between Heating and Cooling

Autor: Wang, Hai-Yang, Bai, Xue-Ning, Lai, Dong, Lin, Douglas N. C.

Hydrodynamical interaction in circumbinary discs (CBDs) plays a crucial role in various astrophysical systems, ranging from young stellar binaries to supermassive black hole binaries in galactic centers. Most previous simulations of binary-disc syste

On the Role of Gas Cooling in the Dynamics of Circumbinary Disks

Autor: Wang, Hai-Yang, Bai, Xue-Ning, Lai, Dong

Hydrodynamical interactions between binaries and circumbinary disks (CBDs) play an important role in a variety of astrophysical systems, from young stellar binaries to supermassive black hole binaries. Previous simulations of CBDs have mostly employe
