The Parkes Observatory Pulsar Data Archive

Lawrence Toomey, George Hobbs, James Dempsey +3

Data from observations of pulsars made by Murriyang, the CSIRO Parkes 64-metre radio-telescope over the last three decades are more accessible than ever before, largely due to thei…

Simulating high-time resolution radio-telescope observations

Rui Luo, George Hobbs, Suk Yee Yong +10

We describe a new software package for simulating channelised, high-time resolution data streams from radio telescopes. The software simulates data from the telescope and observing…

Applying saliency-map analysis in searches for pulsars and fast radio bursts

C. Zhang, C. Wang, G. Hobbs +9

To investigate the use of saliency-map analysis to aid in searches for transient signals, such as fast radio bursts and individual pulses from radio pulsars. We aim to demonstrate…

The Parkes Pulsar Timing Array Project: Second data release

M. Kerr, D. J. Reardon, G. Hobbs +27

We describe 14 years of public data from the Parkes Pulsar Timing Array (PPTA), an ongoing project that is producing precise measurements of pulse times of arrival from 26 millisec…

An ultra-wide bandwidth (704 to 4032 MHz) receiver for the Parkes radio telescope

G. Hobbs, R. N. Manchester, A. Dunning +69

We describe an ultra-wide-bandwidth, low-frequency receiver ("UWL") recently installed on the Parkes radio telescope. The receiver system provides continuous frequency coverage fro…

A pulsar-based timescale from the International Pulsar Timing Array

G. Hobbs, L. Guo, R. N. Caballero +56

We have constructed a new timescale, TT(IPTA16), based on observations of radio pulsars presented in the first data release from the International Pulsar Timing Array (IPTA). We us…

Wide-band Profile Domain Pulsar Timing Analysis

L. Lentati, M. Kerr, S. Dai +22

We extend profile domain pulsar timing to incorporate wide-band effects such as frequency-dependent profile evolution and broadband shape variation in the pulse profile. We also in…

From Spin Noise to Systematics: Stochastic Processes in the First International Pulsar Timing Array Data Release

L. Lentati, R. M. Shannon, W. A. Coles +80

We analyse the stochastic properties of the 49 pulsars that comprise the first International Pulsar Timing Array (IPTA) data release. We use Bayesian methodology, performing model…

The International Pulsar Timing Array: First Data Release

J. P. W. Verbiest, L. Lentati, G. Hobbs +89

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 m…

Versatile Directional Searches for Gravitational Waves with Pulsar Timing Arrays

D. R. Madison, X. -J. Zhu, G. Hobbs +23

By regularly monitoring the most stable millisecond pulsars over many years, pulsar timing arrays (PTAs) are positioned to detect and study correlations in the timing behaviour of…
