Description
Precious information about the history of cosmological magnetic fields comes from their observation in the large scale structure of the Universe. Diffuse synchrotron emission represents a powerful tool to constrain the strength and geometry of the magnetic fields in clusters and in filaments of the cosmic web. A complementary probe is the Faraday effect on the signal of background radio sources, caused by clusters and filaments in front of the radio sources themselves. During this talk, I will present recent results on the study of magnetic fields in galaxy clusters and filaments, obtained with new generation instruments and advanced techniques of analysis and interpretation. I will present as well future perspectives with the SKA telescope.
