This study investigates the gravitational wave production induced by primordial magnetic fields in a parity-violating magnetogenesis model and examines their relationship. The research suggests that detectable gravitational waves by LISA, DECIGO, or BBO and strong enough magnetic fields to explain blazar observations can be simultaneously produced and have the same chirality. The amplitudes of the magnetic fields and gravitational waves are related, which can be tested by future observations.
We investigate the gravitational wave production induced by the primordial magnetic fields in a parity-violating magnetogenesis model. It is shown that the gravitational waves detectable by LISA, DECIGO or BBO and the magnetic fields strong enough to explain the blazar observation can be simultaneously produced. The magnetic fields and the gravitational waves have the same chirality and their amplitudes are related, which may also be tested by future observations.
