Mitigating cosmic variance in the Hellings-Downs curve: a Cosmic Microwave Background analogy
Cyril Pitrou, Giulia Cusin
The Hellings-Downs (HD) correlation, which characterizes the signature of a stochastic gravitational wave background measured via Pulsar Timing Arrays (PTA), is derived using a har…
The impact of large-scale galaxy clustering on the variance of the Hellings-Downs correlation: numerical results
Nastassia Grimm, Martin Pijnenburg, Giulia Cusin +1
Pulsar timing array experiments have recently found evidence for a stochastic gravitational wave (GW) background, which induces correlations among pulsar timing residuals described…
Boosting gravitational waves: a review of kinematic effects on amplitude, polarization, frequency and energy density
Giulia Cusin, Cyril Pitrou, Camille Bonvin +2
We review the kinematic effects on a gravitational wave due to either a peculiar motion of the astrophysical source emitting it or a local motion of the observer. Working in the co…
Wave optics lensing of gravitational waves: theory and phenomenology of triple systems in the LISA band
Martin Pijnenburg, Giulia Cusin, Cyril Pitrou +1
We study lensing of gravitational waves by a black hole in the deep wave optics regime, i.e. when the wavelength is much larger than the black hole Schwarzschild radius. We apply i…
The impact of large-scale galaxy clustering on the variance of the Hellings-Downs correlation: theoretical framework
Nastassia Grimm, Martin Pijnenburg, Giulia Cusin +1
While pulsar timing array experiments have recently found evidence for the existence of a stochastic gravitational wave (GW) background, its origin is still unclear. If this backgr…
