Strong-field Gravity Tests with the Double Pulsar
M. Kramer, I. H. Stairs, R. N. Manchester +27
Continued observations of the Double Pulsar, PSR J0737-3039A/B, consisting of two radio pulsars (A and B) that orbit each other with a period of 2.45hr in a mildly eccentric (e=0.0…
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…
Removal and replacement of interference in tied-array radio pulsar observations using the spectral kurtosis estimator
M. Purver, C. G. Bassa, I. Cognard +10
We describe how to implement the spectral kurtosis method of interference removal (zapping) on a digitized signal of averaged power values. Spectral kurtosis is a hypothesis test,…
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…
Search for Very High-Energy Emission from the millisecond pulsar PSR J0218+4232
V. A. Acciari, S. Ansoldi, L. A. Antonelli +198
PSR J0218+4232 is one of the most energetic millisecond pulsars known and has long been considered as one of the best candidates for very high-energy (VHE; >100 GeV) gamma-ray emis…
