Why haven't the observed high-frequency QPOs been produced by (MHD) computer simulations of black hole accretion disks? [HEAP]

http://arxiv.org/abs/2112.01415


We compare some predictions of Wagoner & Tandon (2021) with the results of the hydrodynamic and magnetohydrodynamic (MHD) simulations of Reynolds & Miller (2009). It appears that the MHD simulations were not run for long enough and the numerical damping was not small enough to produce the observed high-frequency QPOs (and the g-mode seen in the hydro simulations).
