3 GHz radio contours from the VLASS survey (in cyan) overlaid on the 0.5–7 keV X-ray image of PSO J0309+27 from the 128 ksec Chandra observation. The count colour scale is displayed on the right. For display purposes, only the (3, 3, 6) × the off-source RMS (=0.12 mJy beam⁻¹) radio contours are reported. The dashed green circle and the solid blue ellipse are the regions used for the extraction of the core and the jet X-ray spectra, respectively.
