Insights into the Pulsar Timing Array hypothesis space
El Mehdi Zahraoui, Patricio Maturana-Russel, Willem van Straten +2
We present novel insights into the pulsar-noise model space in pulsar timing array (PTA) experiments. Through a comparative analysis of the same Parkes PTA second data release obse…
Enhancing evidence estimation through informed probability density approximation
El Mehdi Zahraoui, Patricio Maturana-Russel, Avi Vajpeyi +3
We introduce the Morph approximation, a class of product approximations of probability densities that selects low-order disjoint parameter blocks by maximizing the sum of their tot…
The polarimetric response of the Nançay Radio Telescope and its impact on precision pulsar timing
Lucas Guillemot, Willem van Straten, Ismaël Cognard +3
In \citet{Guillemot2023} we presented a new method for calibrating pulsar observations conducted with the Nançay decimetric Radio Telescope (NRT), which significantly improved NRT…
Tackling artefacts in the timing of relativistic pulsar binaries: towards the SKA
Huanchen Hu, Nataliya K. Porayko, Willem van Straten +3
Common signal-processing approximations produce artefacts when timing pulsars in relativistic binary systems, especially edge-on systems with tight orbits, such as the Double Pulsa…
The High Time Resolution Universe Pulsar Survey-XIX. A coherent GPU accelerated reprocessing and the discovery of 71 pulsars in the Southern Galactic plane
R. Sengar, M. Bailes, V. Balakrishnan +19
We have conducted a GPU accelerated reprocessing of of the archival data from the High Time Resolution Universe South Low Latitude (HTRU-S LowLat) pulsar survey by impl…
