Continuous gravitational waves (GWs) of neutrons stars haven't been detected directly until now. One possible way to indirectly identify their signatures is via the correlation between magnetars and gamma-ray bursts (GRBs), since, under…
The X-ray plateau emission observed in many Long gamma-ray bursts (LGRBs) has been usually interpreted as the spin-down luminosity of a rapidly spinning, highly magnetized neutron star (millisecond magnetar). If this is true, then the…
The most strongly magnetized neutron stars, the magnetars, have spectacular outbursts of gamma-ray flares powered by decay of the magnetic field. The rapidly changing field is strong enough that it should be able to stress and rupture the…
