Radial profiles of rest-mass density ρ (in arbitrary code units), dimensionless fluid temperature Θ ≡ pg/(ρc2), fluid entropy s, radial velocity vr, specific angular momentum uϕ, specific energy ut, magnetic field strength squared b2, inverse plasma-beta ﹩{\beta }_{p}^{-1}\equiv ({b}^{2}/2)/{p}_{g}﹩, and the density scale height h/r. The solid (dashed) lines represent MAD (SANE) simulations. Different colors correspond to different spins. Note that the units of rest-mass density in our simulations are arbitrary—a consequence of the scale-free nature of ideal GRMHD simulations—and therefore the absolute values of 〈ρ〉 have limited physical significance. One should instead focus on the structure of the radial profile.
