Schematic diagram illustrating a possible connection between QPE and RNT systems. QPEs exhibit short recurrence timescales, typically ranging from hours to days, while RNTs show much longer recurrence timescales of months to years. In both cases, recurrent flares may be associated with repeated orbital interactions around SMBHs. The luminosity and time axes are schematic and not to scale.
