Moment maps of the sample. From top to bottom: NGC 4945, Circinus, and NGC 7582. From left to right: Integrated surface brightness map in units of 10⁻²⁰ erg cm⁻² s⁻¹ arcsec⁻², intensity-weighted velocity and velocity dispersion. The first row shows the [NII]λ6584 emission in NGC 4945 and the last two rows refers to the [OIII]λ5007 emission. North is up. The maps are 1 spaxel−σ spatially re-smoothed, so as to get a better visual output, and pixels with S/N ≥ 3 are masked. The maps are obtained from the spectroscopic analysis of the modelled emission line from MUSE data (e.g., Marasco et al. 2020).
