The impact of evolving dark energy on the Weyl potential measured from the Dark Energy Survey Year 3 data
Benedetta Rosatello, Gen Ye, Maria Berti +3
Measurements from the Dark Energy Survey (DES) Year 3 data have shown that the Weyl potential -- the sum of the spatial and temporal distortions of the geometry -- evolves more slo…
A novel test of gravity: Does spacetime geometry track matter density?
Camille Bonvin, Nastassia Grimm, Isaac Tutusaus
We propose a novel test of gravity that combines galaxy clustering with gravitational lensing. In general relativity, the evolution of matter density fluctuations and of the Weyl p…
Comparing the motion of dark matter and standard model particles on cosmological scales
Nastassia Grimm, Camille Bonvin, Isaac Tutusaus
Since dark matter particles have never been directly detected, we do not know how they move, and in particular we do not know how they fall inside gravitational potential wells. Us…
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…
Probing CDM through the Weyl potential and machine learning forecasts
Rubén Arjona, Savvas Nesseris, Isaac Tutusaus +2
For years, the cosmological constant and cold dark matter (CDM) model () has stood as a cornerstone in modern cosmology and serves as the predominant theoretical f…
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…
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…
Testing General Relativity through the Statistic Using the Weyl Potential and Galaxy Velocities
Nastassia Grimm, Camille Bonvin, Isaac Tutusaus
We combine measurements of galaxy velocities from galaxy surveys with measurements of the Weyl potential from the Dark Energy Survey to test the consistency of General Relativity a…
Measurement of the Weyl potential evolution from the first three years of Dark Energy Survey data
Isaac Tutusaus, Camille Bonvin, Nastassia Grimm
The Weyl potential, which is the sum of the spatial and temporal distortions of the Universe's geometry, provides a direct way of testing the theory of gravity and the validity of…
The Gravitational Universe
The eLISA Consortium, :, P. Amaro Seoane +158
The last century has seen enormous progress in our understanding of the Universe. We know the life cycles of stars, the structure of galaxies, the remnants of the big bang, and hav…
