Caption: Figure 4.
Compilation of minihalos from A. Richard-Laferrière et al. (2020), along with the best fit shown with the solid line, also from A. Richard-Laferrière et al. (2020). The minihalo radio power (P1.4 GHz) is shown as a function of X-ray luminosity within a radius of 600 kpc (LX). SpARCS1049+56 is represented by the blue star. Here, we used the flux density at 144 MHz from the LOFAR 6″ image and extrapolated it to 1.4 GHz, while the X-ray luminosity was estimated using XMM-Newton observations.
