| contents | Supermassive black hole (SMBH) binaries in gaseous and stellar environments are prime targets for next-generation space-based gravitational wave detectors. Yet, realistic accretion conditions under which these binary systems evolve are not fully understood. In this work, we demonstrate the hypermagnetized multi-phase nature of the surrounding accretion flow formed by large-scale feeding from a galaxy background. Our simulations indicate that the hypermagnetized circumbinary disk is eccentric and warped, hosting a hot gas core for a parsec-scale separated binary. We also observe collimated bipolar magnetic tower-like outflows launched from each SMBH. |
