Analysis
This paper proposes a novel model for the formation of double-double radio galaxies (DDRGs), suggesting that the observed inner and outer jets are linked by continuous accretion, even during the quiescent phase. The authors argue that the black hole spin plays a crucial role, with jet formation being dependent on spin and the quiescent time correlating with the subsequent jet duration. This challenges the conventional view of independent accretion events and offers a compelling explanation for the observed correlations in DDRGs.

Reference
“The authors show that a correlation between the quiescent time and the inner jet time may exist, which they interpret as resulting from continued accretion through the quiescent jet phase.”
