Can long-term periodic variability and jet helicity in 3C 120 be explained by jet precession?
Anderson Caproni, Zulema Abraham
Optical variability of 3C 120 is discussed in the framework of jet precession. Specifically, we assume that the observed long-term periodic variability is produced by the emission…

Precession in the inner jet of 3C 345
Anderson Caproni, Zulema Abraham
VLBI observations have shown that the parsec-jet of 3C 345 is formed by several components, ejected from the core with superluminal velocities and travelling along bent trajectorie…
