Top row: Radial surface density profiles (integrated and averaged over 800 Myr) for different ISM phases in our Stellar Feedback simulations (see Table 2). The radius R is with respect to the position of the MBH, and the calculation of surface densities are limited to gas inside |z|< 300 pc of the MBH. Bottom row: Corresponding mass fraction as a function of radius for each ISM phase in the top row. Shaded areas correspond to one standard deviation (±σ).
