                         high ionized gas in the Circinus Galaxy by means of the coronal 
                         line (CL) [Fe vii] lambda 6087. This emission is located within 
                         the ionization cone already detected in the [O iii] lambda 5007 
                         line and is found to extend up to a distance of similar to 700 pc 
                         from the active galactic nucleus. The gas distribution appears 
                         clumpy, with several knots of emission. Its kinematics is complex, 
                         with split profiles and line centroids shifted from the systemic 
                         velocity. The physical conditions of the gas show that the 
                         extended coronal emission is likely the remnant of shells inflated 
                         by the passage of a radio jet. This scenario is supported by 
                         extended X-ray emission, which is spatially coincident with the 
                         morphology and extension of the [Fe vii] lambda 6087 gas in the NW 
                         side of the galaxy. The extension of the coronal gas in the 
                         Circinus galaxy is unique among active galaxies and demonstrates 
                         the usefulness of CLs for tracing the shock ionization component 
                         in these objects.",
