Compact obscured nuclei (CONs) are relatively common in the centers of local(U)LIRGs, yet their nature remains unknown. Both AGN activity and extremenuclear starbursts have been suggested as plausible nuclear power sources. Theprevalence of outflows in these systems suggest that CONs represent a key phasein the nuclear feedback cycle, in which material is ejected from the centralregions of the galaxy. Here, we present results from MUSE for the confirmedlocal CON galaxy NGC4418. For the first time we spatially map the spectralfeatures and kinematics of the galaxy in the optical, revealing severalpreviously unknown structures. In particular, we discover a bilateral outflowalong the minor axis, an outflowing bubble, several knot structures and areceding outflow partially obscured by the galactic disk. Based on theproperties of these features, we conclude that the CON in NGC4418 is mostlikely powered by an AGN.
