Stochastic gravitational-wave background search using data from five pulsar timing arrays
Wang-Wei Yu, Bruce Allen
Using public pulse time-of-arrival data from five pulsar timing arrays (PTAs), we search for a stationary, isotropic, and unpolarized nHz stochastic gravitational-wave background (…
Pulsar timing array analysis in a Legendre polynomial basis
Bruce Allen, Arian L. von Blanckenburg, Ken D. Olum
We use Legendre polynomials, previously employed in this context by Lee et al., van Haasteren and Levin, and Pitrou and Cusin, to model signals in pulsar timing arrays. These repla…
Optimal robust detection statistics for pulsar timing arrays
Rutger van Haasteren, Bruce Allen, Joseph D. Romano
Pulsar timing arrays (PTAs) seek to detect a nano-Hz stochastic gravitational-wave background (GWB) by searching for the characteristic Hellings and Downs angular pattern of timing…
Harmonic spectrum of pulsar timing array angular correlations
Bruce Allen, Joseph D. Romano
Pulsar timing arrays (PTAs) detect gravitational waves (GWs) via the correlations they create in the arrival times of pulses from different pulsars. The mean correlation, a functio…
