Coherent Search for Binary Pulsars across all Five Keplerian Parameters in Radio Observations using the template-bank algorithm
Vishnu Balakrishnan, David Champion, Ewan Barr +5
Relativistic binary pulsars orbiting white dwarfs and neutron stars have already provided excellent tests of gravity. However, despite observational efforts, a pulsar orbiting a bl…
No Pulsar Companion Around the Nearest Low Mass White Dwarf
Tilemachos M. Athanasiadis, Nataliya K. Porayko, John Antoniadis +5
2MASS J050051.85093054.9 is the closest known low-mass helium-core white dwarf in a binary system. We used three high-band international LOFAR stations to perform a targeted sea…
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…
Noise analysis in the European Pulsar Timing Array data release 2 and its implications on the gravitational-wave background search
A. Chalumeau, S. Babak, A. Petiteau +49
The European Pulsar Timing Array (EPTA) collaboration has recently released an extended data set for six pulsars (DR2) and reported evidence for a common red noise signal. Here we…
Common-red-signal analysis with 24-yr high-precision timing of the European Pulsar Timing Array: Inferences in the stochastic gravitational-wave background search
S. Chen, R. N. Caballero, Y. J. Guo +49
We present results from the search for a stochastic gravitational-wave background (GWB) as predicted by the theory of General Relativity using six radio millisecond pulsars from th…
Astronomical Pipeline Provenance: A Use Case Evaluation
Michael A. C. Johnson, Marcus Paradies, Marta Dembska +4
In this decade astronomy is undergoing a paradigm shift to handle data from next generation observatories such as the Square Kilometre Array (SKA) or the Vera C. Rubin Observatory…
