The intracluster magnetic field power spectrum in Abell 2382

Understand

The goal of this work is to put constraints on the strength and structure of the magnetic field in the cluster of galaxies A2382.

• We investigate the relationship between magnetic field and Faraday rotation effects in the cluster, using numerical simulations as a reference for the observed polarization properties.
• For this purpose we present Very Large Array observations at 20 cm and 6 cm of two polarized radio sources embedded in A2382, and we obtained detailed rotation measure images for both of them.
• We simulated random three-dimensional magnetic field models with different power spectra and thus produced synthetic rotation measure images.
