cds-question@unistra.frradio-galaxiesradio-sourcesWe present a multi-wavelength study of the gaseous medium surrounding the nearby active galactic nucleus (AGN), Fornax A. Using MeerKAT, ALMA, and MUSE observations, we reveal a complex distribution of the atomic (HI), molecular (CO 1-0), and ionised gas in its centre and along the radio jets. By studying the multi-scale kinematics of the multi-phase gas, we reveal the presence of concurrent AGN feeding and feedback phenomena. Several clouds and an extended 3kpc filament - perpendicular to the radio jets and the inner disc (r<4.5kpc) - show highly-turbulent kinematics, which likely induces non-linear condensation and subsequent chaotic cold accretion (CCA) onto the AGN. In the wake of the radio jets and in an external (r>4.5kpc) ring, we identify an entrained massive (~10^7^M_{sun}_) multi-phase outflow (v_OUT_~2000km/s^). The rapid flickering of the nuclear activity of Fornax A (~3Myr) and the gas experiencing turbulent condensation raining onto the AGN provide quantitative evidence that a recurrent, tight feeding and feedback cycle may be self-regulating the activity of FORN, in agreement with CCA simulations. To date, this is one of the most in-depth probes of such a mechanism, paving the way to apply these precise diagnostics to a larger sample of nearby AGN hosts and their multi-phase Interstellar Medium.2021A&A...656A..45Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/656/A45CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/656/A45https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/656/A45http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/656/A45https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/656/A45https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/656/A45http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/656/A45GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/656/A45/list (List of fits datacubes)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/656/A45/list?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/656/A45/list?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/656/A45/list?GETtext/xml+votable180.050000true50.6744-37.208480.0055555555555555566/34493https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/656/A45?format=asciiRadiodefaultJ/A+A/656/A45/listList of fits datacubesrecnoRecord number assigned by the VizieR team.
