Energy per unit mass (Γ_∞, Equation (22)) snapshot on large scales for runs NS and HS at time t = 110,700 r_g/c. When a = 0.9375, the BZ jets clear out polar funnels and drive highly relativistic (Γ_∞ ≳ 2–10) outflows. When a = 0, the outflows are mildly relativistic (Γ_∞ ≈ 10⁻²–10⁻¹) and do not clear out a funnel. (a) Γ_∞ in x − z plane for HS. We show the axisymmetrized effective (τ_eff = 1, Equation (23), white solid lines) and scattering (τ_es = 1, Equation (25), white dotted lines) photospheres. We also show a 200 r_g × 200 r_g inset panel of the effective photosphere reaching down to the BH. (b) Same as panel (a), but for NS.
