Pulsar Timing Array Sensitivity to Anisotropy: Empirical Sensitivity Curves, Scaling Relations, and the Multi-Resolution Pixel Basis
Taha T. Moursy, Nihan S. Pol, Gabriella Agazie +115
We quantify pulsar timing array (PTA) sensitivity to anisotropy in the gravitational wave background using the cross-correlation based Fisher information matrix in the pixel and sp…
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…
Likelihoods for Stochastic Gravitational Wave Background Data Analysis
Gabriele Franciolini, Mauro Pieroni, Angelo Ricciardone +1
We present a systematic study of likelihood functions used for Stochastic Gravitational Wave Background (SGWB) searches. By dividing the data into many short segments, one customar…
Optimal reconstruction of the Hellings and Downs correlation
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…
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…
Source anisotropies and pulsar timing arrays
Bruce Allen, Deepali Agarwal, Joseph D. Romano +1
Pulsar timing arrays (PTA) hunt for gravitational waves (GW) by searching for the correlations that GWs induce in the time-of-arrival residuals from different pulsars. If the GW so…
