Comparing recent PTA results on the nanohertz stochastic gravitational wave background

The International Pulsar Timing Array Collaboration, G. Agazie, J. Antoniadis +242

The Australian, Chinese, European, Indian, and North American pulsar timing array (PTA) collaborations recently reported, at varying levels, evidence for the presence of a nanohert…

Search for an isotropic gravitational-wave background with the Parkes Pulsar Timing Array

Daniel J. Reardon, Andrew Zic, Ryan M. Shannon +26

Pulsar timing arrays aim to detect nanohertz-frequency gravitational waves (GWs). A background of GWs modulates pulsar arrival times and manifests as a stochastic process, common t…

Determining electron column density fluctuations in a dominant scattering region using pulsar scintillation

Daniel J. Reardon, William A. Coles

Density fluctuations in the ionised interstellar medium have a profound effect on radio pulsar observations, through angular scattering, intensity scintillations, and small changes…

Pulsar Scintillation Studies with LOFAR: II. Dual-frequency scattering study of PSR J0826+2637 with LOFAR and NenuFAR

Ziwei Wu, William A. Coles, Joris P. W. Verbiest +28

Interstellar scattering (ISS) of radio pulsar emission can be used as a probe of the ionised interstellar medium (IISM) and causes corruptions in pulsar timing experiments. Two typ…

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…
