The LOFAR sub-arcsecond view of the high-redshift radio relic in PSZ2 G091.83+26.11

Context. Enhanced inverse Compton losses at high redshift are expected to steepen the spectrum of diffuse radio sources in galaxy clusters, making low-frequency (ν ∼ 100 MHz) observations favourable. However, observations at these low frequencies suffer from limitations due to resolution, which affe...
