Description
Monopoles are inevitable predictions of GUT theories. They are produced during phase transitions in the early universe, but also mechanisms like Schwinger effect in strong magnetic fields could give relevant contributions to the monopole number density. I will show that from the detection of intergalactic magnetic fields of primordial origin we can infer additional bounds on the magnetic monopole flux at present time. I will also discuss the implications of these bounds for millicharged monopoles and for magnetic monopole pair production in primordial magnetic fields.
