We investigated the interstellar medium (ISM) properties in the central
regions of nearby Seyfert galaxies characterised by prominent conical or
bi-conical outflows belonging to the MAGNUM survey by exploiting the
unprecedented sensitivity, spatial and spectral coverage of the integral field
spectrograph MUSE at the Very Large Telescope. We developed a novel approach
based on the gas and stars kinematics to disentangle high-velocity gas in the
outflow from gas in the disc to spatially track the differences in their ISM
properties. This allowed us to reveal the presence of an ionisation structure
within the extended outflows that can be interpreted with different
photoionisation and shock conditions, and to trace tentative evidence of
outflow-induced star formation (”positive” feedback) in a galaxy of the
sample, Centaurus A.
