The SKAO Pulsar Timing Array
Ryan M. Shannon, N. D. Ramesh Bhat, Aurélien Chalumeau +22
Pulsar timing arrays (PTAs) are ensembles of millisecond pulsars observed for years to decades. The primary goal of PTAs is to study gravitational-wave astronomy at nanohertz frequ…
A comparative analysis of pulse time-of-arrival creation methods
J. Wang, G. M. Shaifullah, J. P. W. Verbiest +15
Extracting precise pulse times of arrival (TOAs) and their uncertainties is the first and most fundamental step in high-precision pulsar timing. In the classical method, TOAs are d…
Pulsars with NenuFAR: backend and pipelines
L. Bondonneau, J. -M. Grießmeier, G. Theureau +27
NenuFAR (New extension in Nançay upgrading LoFAR) is a new radio telescope developed and built on the site of the Nançay Radio Observatory. It is designed to observe the largely un…
Testing the accuracy of the ionospheric Faraday rotation corrections through LOFAR observations of bright northern pulsars
N. K. Porayko, A. Noutsos, C. Tiburzi +13
Faraday rotation of polarized emission from pulsars measured at radio frequencies provides a powerful tool to investigate the interstellar and interplanetary magnetic fields. Howev…
The High Time Resolution Universe survey XIV: Discovery of 23 pulsars through GPU-accelerated reprocessing
V. Morello, E. D. Barr, S. Cooper +21
We have performed a new search for radio pulsars in archival data of the intermediate and high Galactic latitude parts of the Southern High Time Resolution Universe pulsar survey.…
Pulsars probe the low-frequency gravitational sky: Pulsar Timing Arrays basics and recent results
Caterina Tiburzi
Pulsar Timing Array (PTA) experiments exploit the clock-like behaviour of an array of millisecond pulsars, with the goal of detecting low-frequency gravitational waves. PTA experim…
The SUrvey for Pulsars and Extragalactic Radio Bursts I: Survey Description and Overview
E. F. Keane, E. D. Barr, A. Jameson +19
We describe the Survey for Pulsars and Extragalactic Radio Bursts (SUPERB), an ongoing pulsar and fast transient survey using the Parkes radio telescope. SUPERB involves real-time…
The Sardinia Radio Telescope: From a Technological Project to a Radio Observatory
I. Prandoni, M. Murgia, A. Tarchi +43
[Abridged] The Sardinia Radio Telescope (SRT) is the new 64-m dish operated by INAF (Italy). Its active surface will allow us to observe at frequencies of up to 116 GHz. At the mom…
The Statistics of Radio Astronomical Polarimetry: Disjoint, Superposed, and Composite Samples
Willem van Straten, Caterina Tiburzi
A statistical framework is presented for the study of the orthogonally polarized modes of radio pulsar emission via the covariances between the Stokes parameters. To accommodate th…
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…
A study of spatial correlations in pulsar timing array data
Caterina Tiburzi, George Hobbs, Matthew Kerr +6
Pulsar timing array experiments search for phenomena that produce angular correlations in the arrival times of signals from millisecond pulsars. The primary goal is to detect an is…
The noise properties of 42 millisecond pulsars from the European Pulsar Timing Array and their impact on gravitational wave searches
R. N. Caballero, K. J. Lee, L. Lentati +36
The sensitivity of Pulsar Timing Arrays to gravitational waves depends on the noise present in the individual pulsar timing data. Noise may be either intrinsic or extrinsic to the…
