EP251023a: A fast X-ray transient featuring a magnetar-powered optical internal plateau followed by a steep decay
Shuai-Qing Jiang, Dong Xu, Wei-Hua Lei +33
EP251023a is an extragalactic fast X-ray transient (eFXT) detected solely by EP without a gamma-ray counterpart. The prompt emission consists of a main emission with a duration $T_…

On the Fast-radio-burst-associated X-ray Bursts: Inverse Compton Scattering of Radio Photons by an Extreme Pair Flow During Magnetosphere Activities
Yue Wu, Yuan-Pei Yang, Fa-Yin Wang +1
The Galactic fast radio burst (FRB) FRB 200428 was associated with a short X-ray burst (XRB) from the magnetar SGR J1935+2154 during one of its active phases. This FRB-associated X…
