Multi-wavelength emission from Mrk 273. The blue contours map the 144 MHz emission from the LOFAR 144 MHz image, red contours map the soft X-ray emission (0.4−2 keV) from L19, overlaid on the optical continuum image from S16 at λ = 6572 Å. The optical continuum tail seen towards the south of the nucleus is marked. The extended soft X-ray nebulae seen in south-west (SW) and north-east (NE) can be seen as well. The Chandra X-ray image has been smoothed with a Gaussian kernel of σ = 10 pixels, using the CIAO package.
