Evaluating the prevalence of spurious correlations in pulsar timing array datasets
Andrew Zic, George Hobbs, R. M. Shannon +13
Pulsar timing array collaborations have recently reported evidence for a noise process with a common spectrum among the millisecond pulsars in the arrays. The spectral properties o…
The Planetary Ephemeris Program: Capability, Comparison, and Open Source Availability
John F. Chandler, James B. R. Battat, Thomas W. Murphy +3
We describe for the first time in the scientific literature the Planetary Ephemeris Program (PEP), an open-source general-purpose astrometric data analysis program. We discuss, in…
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…
Analysis of the ionized interstellar medium and orbital dynamics of PSR~J1909-3744 using scintillation arcs
Jacob Askew, Daniel Reardon, Ryan Shannon
Long-term studies of binary millisecond pulsars (MSPs) provide precise tests of strong-field gravity and can be used to measure neutron-star masses. PSR~J19093744, a binary MSP…
Ultra-Wideband Polarimetry of the April 2021 Profile Change Event in PSR J1713+0747
Rami F. Mandow, Andrew Zic, J. R. Dawson +15
The millisecond pulsar PSR J1713+0747 is a high-priority target for pulsar timing array experiments due to its long-term timing stability, and bright, narrow pulse profile. In Apri…
