Princeton University Astroplasmas Seminar

Galaxy clusters and filaments of the cosmic web are giant and perfect plasma laboratories in the Universe, which can tell us about the growth of cosmic magnetism from either primordial or astrophysical seed field, as well as about the acceleration of cosmic rays by violent accretion processes.

I will review recent results in the numerical modelling of such objects, with the final goal of understanding the mysterious origin of cosmic magnetism, and use existing or future radio observations to test and kill competing theoretical models, spanning from the range of radio jets from AGN to that of giant cosmic filaments.
