Recent radiation-thermochemical-magnetohydrodynamic simulations resolved formation of quasar accretion disks from cosmological scales down to ~300 gravitational radii $R_{g}$, arguing they were 'hyper-magnetized' (plasma $\beta\ll1$ supported by toroidal magnetic fields) and distinct traditional $\alpha$-disks. We extend these, refining $\approx 3\,R_{g}$ around a $10^{7}\,{\rm M_{\odot}}$ BH with multi-channel radiation thermochemistry, exploring factor 1000 range rates...
Abstract Low-frequency gravitational-wave experiments such as the Laser Interferometer Space Antenna and pulsar timing arrays are expected to detect individual massive black hole (MBH) binaries mergers. However, secure methods of identifying exact host galaxy each MBH merger among large number galaxies in localization region currently lacking. We investigate distinct morphological signatures galaxies, using Romulus25 cosmological simulation. produce mock telescope images 201 simulated...
Abstract Secure methods for identifying the host galaxies of individual massive black hole (MBH) binaries and mergers detected by gravitational-wave experiments such as Laser Interferometer Space Antenna pulsar timing arrays are currently lacking, but will be critical to a variety science goals. Recently, in Bardati et al., we used Romulus25 cosmological simulation show that MBH merger have unique morphologies imaging, due their stronger bulges. Here, use same sample simulated investigate...
