J2345–0449 on mega-parsec and kilo-parsec scales. Left: radio-continuum image of J2345–0449 observed with the GMRT at 323 MHz, and showing the relative position and size of the radio source and host galaxy, which we now probe with MUSE. The local rms noise is 0.1 mJy bm⁻¹. Right: SDSS three-color image showing the g, r, and i-bands, with the MUSE Hα contours shown in orange. Small circles in the lower left corner indicate the size of the seeing disk in each channel of the rgb image. The orange circle shows the size of the seeing disk of the Hα image.
