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…
Testing gravity with cosmic variance-limited pulsar timing array correlations
Reginald Christian Bernardo, Kin-Wang Ng
The nanohertz stochastic gravitational wave background (SGWB) is an excellent early universe laboratory for testing the fundamental properties of gravity. In this letter, we elucid…
Hunting the stochastic gravitational wave background in pulsar timing array cross correlations through theoretical uncertainty
Reginald Christian Bernardo, Kin-Wang Ng
Incredible progress on the theoretical uncertainty of the spatial correlations of the stochastic gravitational wave (GW) background were recently made. However, it remains to reali…
Constraining gravitational wave propagation using pulsar timing array correlations
Reginald Christian Bernardo, Kin-Wang Ng
Pulsar timing arrays (PTA) are a promising probe to the cosmologically novel nanohertz gravitational wave (GW) regime through the stochastic GW background. In this work, we conside…
