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…
Scintillation Bandwidth Measurements from 23 Pulsars from the AO327 Survey
Sofia Z. Sheikh, Grayce C. Brown, Jackson MacTaggart +15
A pulsar's scintillation bandwidth is inversely proportional to the scattering delay, making accurate measurements of scintillation bandwidth critical to characterize unmitigated d…
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…
The Pulsar Science Collaboratory: Multi-Epoch Scintillation Studies of Pulsars
Jacob E. Turner, Juan G. Lebron Medina, Zachary Zelensky +13
We report on findings from scintillation analyses using high-cadence observations of eight canonical pulsars with observing baselines ranging from one to three years. We obtain sci…
