Volume-rendering of the inner (20 kpc)³ of our fiducial MHD run at three different times. The yellow and white components represent the isodensity surfaces for $3\times {10}^{-3}{\mathrm{cm}}^{-3}$ and $2\times {10}^{-2}{\mathrm{cm}}^{-3}$, respectively, and trace the outflowing AGN jet material. The blue component traces the cold gas of density $20{\mathrm{cm}}^{-3}$. The figure shows that, even though the AGN jets are accelerated along the vertical axis of this image, interaction with the dense infalling filaments leads to the formation of cavities that move in directions strongly inclined relative to the main jet axis. The round black and white marker at the centre of each panel represents the position of the SMBH particle (movies available online).
