Resumen:
Born-Infeld electromagnetic waves interacting with a staticmagnetic background are studied in an expanding universe. Thenon-linear character of Born-Infeld electrodynamics modifies therelation between the energy flux and the distance to the source,which gains a new dependence on the redshift that is governed bythe background field. We compute the luminosity distance as afunction of the redshift and compare with Maxwellian curves forsupernovae type Ia.
