Simulating a Gaussian stochastic gravitational wave background signal in pulsar timing arrays
Reginald Christian Bernardo, Kin-Wang Ng
We revisit the theoretical modeling and simulation of a Gaussian stochastic gravitational wave background (SGWB) signal in a pulsar timing array (PTA). We show that the correlation…
Charting the Nanohertz Gravitational Wave Sky with Pulsar Timing Arrays
Reginald Christian Bernardo, Kin-Wang Ng
In the summer of 2023, the pulsar timing arrays (PTAs) announced a compelling evidence for the existence of a nanohertz stochastic gravitational wave background (SGWB). Despite thi…
Accurate pulsar timing array residual variances and correlation of the stochastic gravitational wave background
Reginald Christian Bernardo, Kin-Wang Ng
Pulsar timing arrays have reported a compelling evidence of a nanohertz stochastic gravitational wave background. However, the origin of the signal remains undetermined, largely be…
Toward a test of Gaussianity of a gravitational wave background
Reginald Christian Bernardo, Stephen Appleby, Kin-Wang Ng
The degree of Gaussianity of a field offers insights into its cosmological nature, and its statistical properties serve as indicators of its Gaussianity. In this work, we examine t…
