The large-scale magnetic field of our Galaxy can be probed in three dimensions using Faraday rotation of pulsar
The host galaxy of a fast radio burst
The discovery of a fast radio burst is reported and the identification of a fading radio transient lasting ~6 days after the event, which is used to identify the host galaxy and measure the galaxy’s redshift, which provides a direct measurement of the cosmic density of ionized baryons in the intergalactic medium.
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)
The High Time Resolution Universe Pulsar Survey - I. System configuration and initial discoveries
With ∼30 per cent of the mid-latitude survey complete, the 13-beam multibeam receiver on the Parkes Radio Telescope has redetected 223 previously known pulsars and discovered 27 pulsars, five of which are millisecond pulsars.
Timing analysis for 20 millisecond pulsars in the Parkes Pulsar Timing Array
We present timing models for 20 millisecond pulsars in the Parkes Pulsar Timing Array. The precision of the parameter measurements in these models has been improved over earlier results by using
Precision Timing of PSR J0437–4715: An Accurate Pulsar Distance, a High Pulsar Mass, and a Limit on the Variation of Newton's Gravitational Constant
Analysis of 10 years of high-precision timing data on the millisecond pulsar PSR J0437–4715 has resulted in a model-independent kinematic distance based on an apparent orbital period derivative, P_b,
A test of general relativity from the three-dimensional orbital geometry of a binary pulsar
High-precision radio observations of the binary millisecond pulsar PSR J0437-4715 are reported, which establish the three-dimensional structure of its orbit and see the Shapiro delay predicted by general relativity, and the mass of the neutron star and its white dwarf companion is determined.

A detailed description of its functionality, justification of major design decisions, analysis of phase-coherent dispersion removal algorithms, and demonstration of performance on some contemporary microprocessor architectures are presented.
Upper bounds on the low-frequency stochastic gravitational wave background from pulsar timing observations: current limits and future prospects
Using a statistically rigorous analysis method, we place limits on the existence of an isotropic stochastic gravitational wave background using pulsar timing observations. We consider backgrounds
