We present a multi-wavelength study of the gaseous medium surrounding thenearby active galactic nucleus (AGN) Fornax A. Using MeerKAT, ALMA and MUSEobservations we reveal a complex distribution of the atomic (HI), molecular(CO), and ionised gas in its centre and along the radio jets. By studying themulti-scale kinematics of the multi-phase gas, we reveal the presence ofconcurrent AGN feeding and feedback phenomena. Several clouds and an extended 3kpc filament -- perpendicular to the radio jets and the inner disk ($r\lesssim4.5$ kpc) -- show highly-turbulent kinematics, which likely induces nonlinearcondensation and subsequent Chaotic Cold Accretion (CCA) onto the AGN. In thewake of the radio jets and in an external ($r\gtrsim 4.5$ kpc) ring, weidentify an entrained massive ($\sim$ $10^7$ M$_\odot$) multi-phase outflow($v_{\rm OUT}\sim 2000$ km s$^{-1}$). The rapid flickering of the nuclearactivity of Fornax A ($\sim$ 3 Myr) and the gas experiencing turbulentcondensation raining onto the AGN provide quantitative evidence that arecurrent, tight feeding and feedback cycle may be self-regulating the activityof Fornax A, in agreement with CCA simulations. To date, this is one of themost in-depth probes of such a mechanism, paving the way to apply these precisediagnostics to a larger sample of nearby AGN hosts and their multi-phase ISM.
