Signature of a magnetar central engine with precession motion in the X-ray emission of GRB 220711B
Ying-Ze Shan, Xing Yang, Hou-Jun Lü +6
The -ray light curve of long-duration GRB 220711B, is characterized by a multi-peaked structure with a duration lasting 105 seconds. More interestingly, the X-ray afterglo…

Event Rate Density and Luminosity Function of Newborn-Magnetar-Driven X-Ray Transients from Neutron Star Binary Mergers
Le Zou, Ji-Gui Cheng, Rui-Chong Hu +2
X-ray transients (XTs) driven by newborn magnetars from mergers of neutron star binaries (NSBs) were occasionally detected in the narrow-field {\it Chandra} Deep Field-South survey…

Quasi-periodic Oscillations in GRB 210514A: a Case of a Newborn Supra-Massive Precessing Magnetar Collapsing into a Black Hole?
Le Zou, Ji-Gui Cheng
Magnetar is proposed as one of the possible central engines for a gamma-ray burst (GRB). Recent studies show that if a magnetar has a rotational axis misaligned from the magnetic o…
