![]() Finally, we complement the radio data with Chandra X-ray observations in order to compare the thermal and non-thermal emission of the cluster. We combine these data with previously published data from the Low Frequency Array (LOFAR) in the 120–168 MHz band and from the upgraded Giant Metrewave Radio Telescope (uGMRT) at 250–500 and 550–900 MHz. We use Karl Jansky Very Large Array data at 1–4 GHz to investigate the spectral and polarisation properties of the diffuse radio emission. However, the location of this diffuse radio source with respect to the intracluster medium (ICM) distribution and to the cluster centre is not consistent with a simple merger scenario. ![]() This cluster hosts a megaparsec-scale radio halo and an elongated radio source whose morphology resembles that of a radio relic. In this paper, we present the peculiar case of PSZ2 G091.83+26.11 at z = 0.822. Despite the tremendous advances in observations in the last decades, the particle (re-)acceleration and magnetic field amplification mechanisms and the connection with the stage and geometry of the cluster merger are still uncertain.Īims. Diffuse radio emission in galaxy clusters, namely radio halos and radio relics, is usually associated with merger events.
