PySCo-EFT and ECOSMOG-EFT: a tandem of N-body simulation codes for the Effective Field Theory of Dark Energy
Himanish Ganjoo, Yann Rasera, Emilio Bellini +18
Modified gravity theories constitute viable alternatives to the standard cosmological model for explaining the observed late-time accelerated expansion of the Universe. The Effecti…
Probing the Kinematic Dipole with LISA: an analytical treatment
Jacopo Fumagalli, Giulia Cusin, Cyril Pitrou +1
The motion of the Solar System with respect to the cosmic rest frame induces a kinematic dipole in the stochastic gravitational-wave background (GWB). Detecting this signal with sp…
\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…
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…
Combining chirp mass, luminosity distance and sky localisation from gravitational wave events to detect the cosmic dipole
N. Grimm, M. Pijnenburg, S. Mastrogiovanni +3
A key test of the isotropy of the Universe on large scales consists in comparing the dipole in the Cosmic Microwave Background (CMB) temperature with the dipole in the distribution…
