Schematic representation of the three scenarios involving binary SMBHs at the center of the radio galaxy in RBS 797. See Sect. 4.2 for details. Arrows represent jets, while circles represent SMBHs (red indicates an active one, black indicates a quiescent one). Blue lines represent the jet activity in the N–S direction, while green lines represent the jet activity in the E–W direction. The dashed lines in panel 1 reflect the precession of the radio lobes on ∼50 kpc scales.
