Fig. 13


Spectral energy flux density as a function of the frequency. GMRT and EVLA observations (yellow solid circles) from Ainsworth et al. (2014) and Lynch et al. (2013), respectively, are shown together with their fit (yellow dashed line) predicting a synchrotron spectral index of −0.89 ± 0.07 (Ainsworth et al. 2014). The two black shaded regions show the result of our modelling using two different shock velocities with respect to the upstream flow (U = 100 km s-1 and 200 km s-1) and their widths refer to an assumed error of 30% on the value of the hot spot radius, the central value (RHS = 1300 AU, Ainsworth et al. 2014) pinpointed by the white dotted lines. The green shaded areas show the two LOFAR bands (LBA=low band antenna; HBA = high band antenna), and their lower boundary in Sν corresponds to the sensitivity limit using its most extended configuration (van Haarlem et al. 2013).
