Probing gravity with non-linear clustering in redshift space
C. Viglione, P. Fosalba, I. Tutusaus +4
We present the first computation of the gravity model testing parameter on realistic simulated modified gravity galaxy mocks. The analysis is conducted using two twin simulat…
Euclid preparation. Review of forecast constraints on dark energy and modified gravity
Euclid Collaboration, N. Frusciante, M. Martinelli +326
The Euclid mission has been designed to provide, as one of its main deliverables, information on the nature of the gravitational interaction, which determines the expansion of the…
Testing modified gravity with 3x2pt analyses in galaxy mocks
Marc Alemany-Gotor, Cristian Viglione, Pablo Fosalba +1
Stage-IV surveys will enable unprecedented tests of gravity on cosmological scales. However, assuming General Relativity in the analysis of large-scale structure could introduce sy…
Euclid: Relativistic effects in the dipole of the 2-point correlation function
F. Lepori, S. Schulz, I. Tutusaus +130
Gravitational redshift and Doppler effects give rise to an antisymmetric component of the galaxy correlation function when cross-correlating two galaxy populations or two different…
