Pulse Profile Variability of PSR J1022+1001 in NANOGrav Data

William Fiore, Maura A. McLaughlin, Gabriella Agazie +46

Pulse profile stability is a central assumption of standard pulsar timing methods. Thus, it is important for pulsar timing array experiments such as the North American Nanohertz Ob…

A Lower Mass Estimate for PSR J0348+0432 Based on CHIME/Pulsar Precision Timing

Alexander Saffer, Emmanuel Fonseca, Scott Ransom +8

The binary pulsar J0348+0432 was previously shown to have a mass of approximately 2\,, based on the combination of radial-velocity and model-dependent mass parameter…

The NANOGrav 15 yr Data Set: Harmonic Analysis of the Pulsar Angular Correlations

Gabriella Agazie, Jeremy G. Baier, Paul T. Baker +86

Pulsar timing array observations have found evidence for an isotropic gravitational wave background with the Hellings-Downs angular correlations, expected from general relativity.…

The NANOGrav 15 yr Data Set: Looking for Signs of Discreteness in the Gravitational-wave Background

Gabriella Agazie, Akash Anumarlapudi, Anne M. Archibald +97

The cosmic merger history of supermassive black hole binaries (SMBHBs) is expected to produce a low-frequency gravitational wave background (GWB). Here we investigate how signs of…

The NANOGrav 12.5-Year Data Set: Probing Interstellar Turbulence and Precision Pulsar Timing with PSR J1903+0327

Abra Geiger, James M. Cordes, Michael T. Lam +33

Free electrons in the interstellar medium refract and diffract radio waves along multiple paths, resulting in angular and temporal broadening of radio pulses that limits pulsar tim…

Exploring pulsar timing precision: A comparative study of polarization calibration methods for NANOGrav data from the Green Bank Telescope

Lankeswar Dey, Maura A. McLaughlin, Haley M. Wahl +32

Pulsar timing array experiments have recently uncovered evidence for a nanohertz gravitational wave background by precisely timing an ensemble of millisecond pulsars. The next sign…
