The LISA Astrophysics "Disc-IMRI" Code Comparison Project: Intermediate-Mass-Ratio Binaries in AGN-Like Discs
Andrea Derdzinski, Alexander J. Dittmann, Alessia Franchini +16
Upcoming space-based gravitational wave detectors such as LISA, the Laser Interferometer Space Antenna, will be sensitive to extreme- and intermediate-mass-ratio inspirals (EMRIs a…
Electromagnetic variability from circumbinary discs around binary black holes during their post-decoupling epoch
Raphaël Mignon-Risse, Peggy Varniere, Fabien Casse
We present general-relativistic hydrodynamical simulations of inviscid circumbinary discs (CBDs) around near equal-mass binary black holes (BBH) in the binary-disc post-decoupling…
A simple toy model for the electromagnetic variability of lump-dominated circumbinary disks around binary black holes
R. Mignon-Risse, P. Varniere, F. Casse
The electromagnetic detection of circumbinary disks around pre-merger binary black holes (BBHs) relies on theoretical predictions. These are generally obtained through expensive nu…
A catalogue of candidate milli-parsec separation massive black hole binaries from long term optical photometric monitoring
Vincent Foustoul, Natalie A. Webb, Raphaël Mignon-Risse +3
The role of mergers in the evolution of massive black holes is still unclear, and their dynamical evolution, from the formation of pairs to binaries and the final coalescence, carr…
Can we disentangle between the emission of an accretion disc around a single black hole and a circumbinary disc ?
Peggy Varniere, Raphaël Mignon-Risse, Fabien Casse
The detection of gravitational waves from binary black holes (BBHs) started the hunt for their pre-merger electromagnetic emission. In that respect, numerical simulations have been…
