Evolution of the mass flow rate. In the two upper panels we show the evolution of the mass outflow rate (mass flux) in the vertical direction at a height of h = 5 kpc in different radial bins, denoted by different linestyles, for the simulations CRMHD and CRMHD-low. Negative values correspond to net inflow. In the lower panels we show the mass-loading factor and energy loading factors, defined in Eqs. (19)–(22), calculated at the same height as the mass outflow rates and for radii r < 20 kpc.
