A Monte Carlo model of a Kerr black hole corona shows that photon collisions create a dense electron-positron pair cloud concentrated near the black hole, yielding X-ray temperatures, Compton parameters, and 4-10% polarization consistent with binary black hole observations.
Radiative cooling in MADs above a transition accretion rate creates thinner denser filaments with increased efficiency, rendering conventional scale height measures misleading and motivating a new definition based on the polar position of the density maximum.
