WebApr 26, 2024 · In fact, there are no 3D GRMHD simulations available for thin discs of aspect ratios H/R < 0.05, and the thinnest discs so far simulated in 3D GRMHD (0.05 < H/R < 0.1) were aligned, which enabled the vertical wavelength of the MRI to be resolved by a grid focused on the equatorial plane, leading to cells compressed in the θ-direction and ... WebGRMHD simulations in Mościbrodzka et al. explain the Sgr A* radio spectrum and image size primarily by efficient electron heating in the outflow plasma. Ryan et al. ( 2024 ) use general relativistic radiative magnetohydrodynamic (GRRMHD) simulations to model the M87 inner accretion flow and find inverse Compton cooling has a non-negligible ...

WebFor the GRMHD simulation, the electron temperature is provided as a fraction of the fluid temperature, where the fraction depends on how magnetized the gas is in the region, as per the R − β prescription from Equation . For the M87 * model, we chose a R high value of 160 to have a jet-dominated sub-mm image. Webtapir.caltech.edu
WebWe test three dimensional General Relativistic Magnetohydrodynamics (GRMHD) simulations of magnetized gas around a supermassive, spinning black hole (the dimen-sionless spin of the black hole is a∗ ≈ 0.94). Our model extends from the black hole horizon to radius of 240 R g (where R g =GM BH/c2) which corresponds to size of 20AU
