Description
In this talk, I will present are results from LOFAR HBA observations of the mini halo in the clutter RBS797
The cluster is known to host a powerful AGN at its centre with two pairs of jet propagating in orthogonal directions. We have investigated the radio emission, classified as radio min halo, and its connection with the central AGN.
We have found an unexpected trend for the spectral index behaviour of the min halo, and propose three different scenarios to explain it. A detailed knowledge of the magnetic field would be fundamental to discriminate between the three scenarios. I will then show preliminary results on the cluster A2034, demonstrating the power of MeerKAT L-band observations to constrain magnetic fields in galaxy clusters.
