Magnetars are the strongest magnets in the present universe and the combination of
extreme magnetic field, gravity and density makes them unique laboratories to probe current …

Two classes of X-ray pulsars, the anomalous X-ray pulsars and the soft gamma-ray
repeaters, have been recognized in the last decade as the most promising candidates for …

Fast radio bursts (FRBs) at cosmological distances have recently been discovered, whose
duration is about milliseconds. We argue that the observed short duration is difficult to …

Soft-γ-ray repeaters (SGRs) are galactic X-ray stars that emit numerous short-duration
(about 0.1 s) bursts of hard X-rays during sporadic active periods. They are thought to be …

The localization of the short-duration, hard-spectrum gamma-ray burst GRB 050509b by the
Swift satellite was a watershed event. We report the discovery of the probable host galaxy, a …

Since the successful launch of NASA's dedicated gamma-ray burst (GRB) mission, Swift, the
study of cosmological GRBs has entered a new era. Here I review the rapid observational …

We have discovered rapid quasi-periodic oscillations (QPOs) in RXTE/PCA measurements
of the pulsating tail of the 2004 December 27 giant flare of SGR 1806-20. QPOs at~ 92.5 Hz …

We report the discovery of complex high-frequency variability during the 1998 August 27
giant flare from SGR 1900+ 14 using the Rossi X-Ray Timing Explorer (RXTE). We detect …

Research work on the global electrical circuit (GEC) is reviewed, with an emphasis on the
period since the last International Conference on Atmospheric Electricity (ICAE) in Beijing …

Young and rotation-powered neutron stars (NSs) are commonly observed as rapidly-
spinning pulsars. They dissipate their rotational energy by emitting pulsar wind with …
