\textit{Euclid}: From Galaxies to Gravitational Waves -- Forecasting Stochastic Gravitational Wave Background Anisotropies and Their Cross-Correlation
K. Z. Yang, G. Cusin, V. Mandic +141
We estimate the amplitude and spatial anisotropy in the stochastic gravitational wave background (SGWB) energy density due to compact binary coalescence (CBC) events: binary black…
Measuring anisotropies in the PTA band with cross-correlations
Giulia Cusin, Cyril Pitrou, Martin Pijnenburg +1
The astrophysical gravitational wave background in the nanohertz (nHz) band is expected to be primarily composed of the superposition of signals from binaries of supermassive black…
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…
