A 30-jansky dispersed burst, less than 5 milliseconds in duration, located 3° from the Small Magellanic Cloud is found, which implies that it was a singular event such as a supernova or coalescence of relativistic objects.
A statistical study of 233 pulsar proper motions
We present and analyse a catalogue of 233 pulsars with proper motion measurements. The sample contains a wide variety of pulsars including recycled objects and those associated with globular clusters…
An increased estimate of the merger rate of double neutron stars from observations of a highly relativistic system
This work reports the discovery of a 22-ms pulsar, PSR J0737–3039, which is a member of a highly relativistic double-neutron-star binary with an orbital period of 2.4 hours, which implies an order-of-magnitude increase in the predicted merger rate for double- NEUTron- star systems in the authors' Galaxy (and in the rest of the Universe).
A Radio Pulsar/X-ray Binary Link
From X-ray Binary to Pulsar Pulsars with millisecond rotational periods are thought to originate from neutron stars in low-mass x-ray binaries that had their spin frequencies increased by…
A Double-Pulsar System: A Rare Laboratory for Relativistic Gravity and Plasma Physics
The detection of the 2.8-second pulsar J0737–3039B as the companion to the 23-millisecond pulsars in a highly relativistic double neutron star system, allowing unprecedented tests of fundamental gravitational physics.

Fast Radio Burst Discovered in the Arecibo Pulsar ALFA Survey
Recent work has exploited pulsar survey data to identify temporally isolated, millisecond-duration radio bursts with large dispersion measures (DMs). These bursts have been interpreted as arising…
Relativistic Shapiro delay measurements of an extremely massive millisecond pulsar
Despite its importance to our understanding of physics at supranuclear densities, the equation of state (EoS) of matter deep within neutron stars remains poorly understood. Millisecond pulsars (MSPs)…
Multifrequency Observations of Radio Pulse Broadening and Constraints on Interstellar Electron Density Microstructure
We have made observations of 98 low Galactic latitude pulsars to measure pulse broadening caused by multipath propagation through the interstellar medium. Data were collected with the 305 m Arecibo…
