NGC 5141 X-ray image in the 0.5–7.0 keV band using a logarithmic scale with σ = 2 pixels of Gaussian smoothing and a scale parameter value ≥0.035 counts per pixel. Left panel: three main X-ray features can be identified: (i) the nuclear region; (ii) an extended diffuse gas emission (cavity rims and western blob); and (iii) a cavity (dashed yellow circle). A zoom of the nonsmoothed nuclear region is shown in the top-right white panel: the core (iv) and the southern jet (v) are clearly visible. The green arrow points to the NGC 5142 optical center. Right panel: optical (dashed white) and radio VLA at 1.4 GHz (green; resolution = 1.4″, RMS = 0.1 mJy beam⁻¹) contours overlap with the X-ray image, after having removed the nuclear emission (2″ × 4″ ellipse, see Sect. 3.2). The cavity position is indicated by the dashed yellow circle. The optical contours are taken from SDSS g-band emission within 70% of the NGC 5141 emitted light. The radio green contours are at −9, 9, 18, 36, 72, 144 × RMS; the image is taken from the NRAO Science Data Archive.
