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…
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…
Gravitational waves or X-ray counterpart? No need to choose
Raphaël Mignon-Risse, Peggy Varniere, Fabien Casse
Binary black holes emit gravitational waves as they inspiral towards coalescence. Searches for electromagnetic counterparts to these gravitational waves rely on looking for common…
On the origin of the lump in circumbinary discs
Raphaël Mignon-Risse, Peggy Varniere, Fabien Casse
Accreting binary black holes (BBHs) are multi-messenger sources, emitting copious electromagnetic (EM) and gravitational waves. One of their most promising EM signatures is the lig…
Impact of a binary black hole on its outer circumbinary disc
Raphaël Mignon-Risse, Peggy Varniere, Fabien Casse
Accreting supermassive binary black holes (SMBBHs) are potential targets for multi-messenger astronomy as they emit gravitational waves (GW) while their environment emits electroma…
A possible imprint of quasi-periodic oscillations in the X-ray spectra of black hole binaries
P. Varniere, R. Mignon-Risse, J. Rodriguez
While nobody would deny the presence of Quasi-Periodic Oscillations in the power density spectrum of Black hole binaries nor their importance in the understanding of the mechanisms…
