Bayesian Geometrical Modeling of IXPE Polarization Angle Curves of the Magnetars 1E 2259+586 and 1E 1547.0-5408
Biao-Peng Li, Zhi-Fu Gao, Wen-Qi Ma +2
X-ray polarimetry directly probes the radiation geometry and large-scale magnetic configuration of magnetars. We present a uniform Bayesian comparison between a dipole-dominated cl…

Studies on the spin and magnetic inclination evolution of magnetars Swift J1834.9-0846 under wind braking
Biaopeng Li, Zhifu Gao, Wenqi Ma +3
The magnetar Swift J1834.9-0846 presents a significant challenge to neutron star spin-down models. It exhibits two key anomalies: an insufficient rotational energy loss rate to pow…
