NGC 1316 (Fornax A) is the brightest galaxy of an infalling subgroup in the outskirts of the Fornax cluster (D=20.8±0.5 Mpc; Cantiello+ 2013). It is the third nearest radio-bright galaxy (Macagni+ 2020), and it hosts an Active Galactic Nuclei (AGN) with extended radio lobes (33 arcmin) (e.g. McKinley+ 2015). The presence of a bent nuclear jet was reported by different authors (e.g. Morokuma-Matsui+ 2019), suggesting an interaction between the jet and the interstellar medium (ISM) of the galaxy. Recently, Macagni+ 2020 proposed that the AGN of NGC 1316 is rapidlyflickering from an active nuclear phase to a non-active one. In this scenario, the central emission detected at radio-frequencies would not be the remnant of the active phases that formed the lobes but it would be tracing the recent activity of the AGN.
