Description
I discuss a late-time magnetogenesis scenario, which takes place after the epoch of electron/positron annihilation. It involves an ultralight axion-like particle, constituting the dark matter of the Universe, and a dark U(1) gauge boson introduced to bypass the obstacle from the relatively high conductivity of the cosmic plasma.
