Non-Gaussian timing residual skewness in pulsar timing arrays
Reginald Christian Bernardo, Rituparna Mandal, Kin-Wang Ng
Motivated by searches for weak primordial non-Gaussianity in the cosmic microwave background, we investigate perturbative departures from Gaussian stochastic gravitational wave bac…
Correlations for an anisotropic polarized stochastic gravitational wave background in pulsar timing arrays
Reginald Christian Bernardo, Guo-Chin Liu, Kin-Wang Ng
The recent compelling observation of the nanohertz stochastic gravitational wave background has brought to light a new galactic arena to test gravity. In this paper, we derive a fo…
Beyond the Hellings-Downs curve: Non-Einsteinian gravitational waves in pulsar timing array correlations
Reginald Christian Bernardo, Kin-Wang Ng
The recent astronomical milestone by the pulsar timing arrays (PTA) has revealed galactic-size gravitational waves (GW) in the form of a stochastic gravitational wave background (S…
