Temporal evolution of the number density of the ambient medium for the three different density slopes of the radial density profile, na = n0(r/r0)−γ, where γ is equal to 0.5, 1.0, and 1.5; see the plot legend. The dashed red lines indicate the number densities that were observationally inferred by Baganoff et al. (2003) (26 cm−3 at the Bondi radius) and Gillessen et al. (2019) (4000 cm−3 at ∼1000 rs).
