Observational Signatures of Binary Supermassive Black Holes
Constanze Roedig, Julian H. Krolik, M. Coleman Miller
Observations indicate that most massive galaxies contain a supermassive black hole, and theoretical studies suggest that when such galaxies have a major merger, the central black h…
Migration of massive black hole binaries in self--gravitating accretion discs: Retrograde versus prograde
Constanze Roedig, Alberto Sesana
We study the interplay between mass transfer, accretion and gravitational torques onto a black hole binary migrating in a self-gravitating, retrograde circumbinary disc. A direct c…
General relativistic radiation hydrodynamics of accretion flows: II. Treating stiff source terms and exploring physical limitations
Constanze Roedig, Olindo Zanotti, Daniela Alic
We present the implementation of an implicit-explicit (IMEX) Runge-Kutta numerical scheme for general relativistic hydrodynamics coupled to an optically thick radiation field in tw…
Evolution of binary black holes in self gravitating discs: dissecting the torques
Constanze Roedig, Alberto Sesana, Massimo Dotti +3
We study the interplay between gas accretion and gravity torques in changing a binary elements and its total angular momentum (L) budget. Especially, we analyse the physical origin…
Origin and Implications of high eccentricities in massive black hole binaries at sub-pc scales
Constanze Roedig, Alberto Sesana
We outline the eccentricity evolution of sub-parsec massive black hole binaries (MBHBs) forming in galaxy mergers. In both stellar and gaseous environments, MBHBs are expected to g…
Multimessenger astronomy with pulsar timing and X-ray observations of massive black hole binaries
A. Sesana, C. Roedig, M. T. Reynolds +1
We demonstrate that very massive (>10^8\msun), cosmologically nearby (z<1) black hole binaries (MBHBs), which are primary targets for ongoing and upcoming pulsar timing arrays (PTA…
