Probing Picohertz Gravitational Waves with Pulsars
Qinyuan Zheng, Chiara M. F. Mingarelli, William DeRocco +3
With periods much longer than the duration of current pulsar timing surveys, gravitational waves in the picohertz (pHz) regime are not detectable in the typical analysis framework…

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.…

Harmonic analysis for pulsar timing arrays
Jonathan Nay, Kimberly K. Boddy, Tristan L. Smith +1
We investigate the use of harmonic analysis techniques to perform measurements of the angular power spectrum on mock pulsar timing data for an isotropic stochastic gravitational-wa…
