Cluster Magnetic Fields from Galactic Outflows

The creation of magnetic fields in shocks through the ”Biermann battery effect ” (Kulsrud et al. 1997; Ryu et al. 1998), and subsequent turbulent dynamo action can be followed as well as a prediction can be made for magnetic field values from velocity fields inferred in cosmological simulations (Ryu et al. 2008). Both methods predict magnetic field strengths in filaments with somearXiv:0808.0919v1
