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…
Generalized Steppingstone Sampling: Efficient marginal likelihood estimation in gravitational wave analysis of Pulsar Timing Array data
El Mehdi Zahraoui, Patricio Maturana-Russel, Willem van Straten +2
Globally, Pulsar Timing Array (PTA) experiments have revealed evidence supporting an existing gravitational wave background (GWB) signal in the PTA data set. Apart from acquiring m…
Reducing instrumental errors in Parkes Pulsar Timing Array data
Axl F. Rogers, Willem van Straten, Sergei Gulyaev +10
This paper demonstrates the impact of state-of-the-art instrumental calibration techniques on the precision of arrival times obtained from 9.6 years of observations of millisecond…
