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 types of gamma-ray bursts (GRBs) are observed: short-duration hard spectrum GRBs
and long-duration soft spectrum GRBs. For many years long GRBs were the focus of intense …

We present a catalog of the 26 currently known magnetars and magnetar candidates. We
tabulate astrometric and timing data for all catalog sources, as well as their observed …

Significant new opportunities for astrophysics and cosmology have been identified at low
radio frequencies. The Murchison Widefield Array is the first telescope in the southern …

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 …

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 …

We present a comprehensive study of the relation between radio and X-ray emission in
neutron star (NS) X-ray binaries, use this to infer the general properties of the disc-jet …

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 have commenced a multiyear program, the Caltech-NRAO Stripe 82 Survey (CNSS), to
search for radio transients with the Jansky VLA in the Sloan Digital Sky Survey Stripe 82 …

We report the discovery of an X-ray pulsar in the young, massive Galactic star cluster
Westerlund 1. We detected a coherent signal from the brightest X-ray source in the cluster …
