Testing Gravity with Pulsars in the SKA Era
Lijing Shao, Ingrid H. Stairs, John Antoniadis +12
The Square Kilometre Array (SKA) will use pulsars to enable precise measurements of strong gravity effects in pulsar systems, which yield tests of gravitational theories that canno…
Three-dimensional Tomography of the Galactic and Extragalactic Magnetoionic Medium with the SKA
J. L. Han, W. van Straten, T. J. W. Lazio +9
The magneto-ionic structures of the interstellar medium of the Milky Way and the intergalactic medium are still poorly understood, especially at distances larger than a few kilopar…
A real-time fast radio burst: polarization detection and multiwavelength follow-up
E. Petroff, M. Bailes, E. D. Barr +32
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 o…
The High Time Resolution Universe Survey - XI. Discovery of five recycled pulsars and the optical detectability of survey white dwarf companions
S. D. Bates, D. Thornton, M. Bailes +20
We present the discovery of a further five recycled pulsar systems in the mid-Galactic latitude portion of the High Time Resolution Universe (HTRU) Survey. The pulsars have rotatio…
Searching for gravitational wave memory bursts with the Parkes Pulsar Timing Array
J. B. Wang, G. Hobbs, W. Coles +17
Anisotropic bursts of gravitational radiation produced by events such as super-massive black hole mergers leave permanent imprints on space. Such gravitational wave "memory" (GWM)…
An all-sky search for continuous gravitational waves in the Parkes Pulsar Timing Array data set
X. -J. Zhu, G. Hobbs, L. Wen +16
We present results of an all-sky search in the Parkes Pulsar Timing Array (PPTA) Data Release 1 data set for continuous gravitational waves (GWs) in the frequency range from $5\tim…
The low-frequency characteristics of PSR J0437-4715 observed with the Murchison Widefield Array
N. D. Ramesh Bhat, S. M. Ord, S. E. Tremblay +37
We report on the detection of the millisecond pulsar PSR J0437-4715 with the Murchison Widefield Array (MWA) at a frequency of 192 MHz. Our observations show rapid modulations of p…
SPINN: a straightforward machine learning solution to the pulsar candidate selection problem
V. Morello, E. D. Barr, M. Bailes +3
We describe SPINN (Straightforward Pulsar Identification using Neural Networks), a high-performance machine learning solution developed to process increasingly large data outputs f…
Limitations in timing precision due to single-pulse shape variability in millisecond pulsars
R. M. Shannon, S. Osłowski, S. Dai +17
High-sensitivity radio-frequency observations of millisecond pulsars usually show stochastic, broadband, pulse-shape variations intrinsic to the pulsar emission process. These vari…
An absence of fast radio bursts at intermediate galactic latitudes
E. Petroff, W. van Straten, S. Johnston +18
Fast radio bursts (FRBs) are an emerging class of bright, highly dispersed radio pulses. Recent work by Thornton et al. (2013) has revealed a population of FRBs in the High Time Re…
Timing, polarimetry and physics of the bright, nearby millisecond pulsar PSR J0437-4715 - a single-pulse perspective
S. Osłowski, W. van Straten, M. Bailes +2
Single pulses from radio pulsars contain a wealth of information about emission and propagation in the magnetosphere and insight into their timing properties. It was recently demon…
The High Time Resolution Universe Pulsar Survey X: Discovery of four millisecond pulsars and updated timing solutions of a further 12
C. Ng, M. Bailes, S. D. Bates +22
We report on the discovery of four millisecond pulsars (MSPs) in the High Time Resolution Universe (HTRU) pulsar survey being conducted at the Parkes 64-m radio telescope. All four…
