ALP-assisted first-order phase transitions can explain observed intergalactic magnetic fields and produce detectable gravitational waves, linking cosmology with particle physics searches.
Plasma instabilities on ~100 kpc scales cool pairs in GeV cascades from 1ES 0229+200, yielding an IGMF strength of order 10^{-17} G when fitted to Fermi-LAT observations.
Superposition of static galactic magnetic dipoles is screened by intergalactic plasma and cannot account for lower bounds on magnetic fields in cosmic voids from blazar gamma-ray data.
