A Population of Fast Radio Bursts at Cosmological Distances
The detection of four nonrepeating radio transient events with millisecond duration in data from the 64-meter Parkes radio telescope in Australia indicates that these radio bursts had their origin outside the authors' galaxy, but it is not possible to tell what caused them.
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 strong magnetic field around the supermassive black hole at the centre of the Galaxy
Multi-frequency radio measurements of a newly discovered pulsar close to the Galactic Centre are reported and it is shown that the pulsar’s unusually large Faraday rotation indicates that there is a dynamically important magnetic field near the black hole.
Formation of Double Neutron Star Systems
Double neutron star (DNS) systems represent extreme physical objects and the endpoint of an exotic journey of stellar evolution and binary interactions. Large numbers of DNS systems and their mergers…
A real-time fast radio burst: polarization detection and multiwavelength follow-up
Fast radio bursts (FRBs) are one of the most tantalizing mysteries of the radio sky; their progenitors and origins remain unknown and until now no rapid multiwavelength follow-up of an FRB has been…
Five new fast radio bursts from the HTRU high-latitude survey at Parkes: First evidence for two-component bursts
The detection of five new fast radio bursts (FRBs) found in the 1.4-GHz High Time Resolution Universe high-latitude survey at Parkes, is presented. The rate implied is 7(-3)(+5) x 10(3) (95 per cent)…
An Eccentric Binary Millisecond Pulsar in the Galactic Plane
In a survey with the Arecibo telescope, a radio pulsar with a rotational period of 2.15 milliseconds in a highly eccentric orbit around a solar mass is found and infrared observations identify a possible main-sequence companion star.
European Pulsar Timing Array Limits On An Isotropic Stochastic Gravitational-Wave Background
We present new limits on an isotropic stochastic gravitational-wave background (GWB) using a six pulsar dataset spanning 18 yr of observations from the 2015 European Pulsar Timing Array data release.…
On the nature and evolution of the unique binary pulsar J1903+0327
PSR J1903+0327, a millisecond pulsar in an eccentric (e = 0.44) 95-d orbit with an ∼ 1M � companion poses a challenge to our understanding of stellar evolution in binary and multiplestar systems.…
The International Pulsar Timing Array: First Data Release
The highly stable spin of neutron stars can be exploited for a variety of (astro)physical investigations. In particular, arrays of pulsars with rotational periods of the order of milliseconds can be…
