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…
Improving Bayesian inference in PTA data analysis: importance nested sampling with Normalizing Flows
Eleonora Villa, Golam Mohiuddin Shaifullah, Andrea Possenti +1
We present a detailed study of Bayesian inference workflows for pulsar timing array data with a focus on enhancing efficiency, robustness and speed through the use of normalizing f…
Improving pulsar timing precision through superior Time-of-Arrival creation
J. Wang, J. P. W. Verbiest, G. M. Shaifullah +6
The measurement of pulsar pulse times-of-arrival (ToAs) is a crucial step in detecting low-frequency gravitational waves. To determine ToAs, we can use template-matching to compare…
The MeerKAT Telescope as a Pulsar Facility: System verification and early science results from MeerTime
M. Bailes, A. Jameson, F. Abbate +72
We describe system verification tests and early science results from the pulsar processor (PTUSE) developed for the newly-commissioned 64-dish SARAO MeerKAT radio telescope in Sout…
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…
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…
