Over recent decades, cosmological simulations of galaxy formation have been instrumental
in advancing our understanding of structure and galaxy formation in the Universe. These …

We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

Horizon-scale images of black holes (BHs) and their shadows have opened an
unprecedented window onto tests of gravity and fundamental physics in the strong-field …

We measure the anisotropic clustering of the quasar sample from Data Release 16 (DR16)
of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey …

Theories of modified gravity, where light scalars with non-trivial self-interactions and non-
minimal couplings to matter—chameleon and symmetron theories—dynamically suppress …

We review recent progress in the construction of modified gravity models as alternatives to
dark energy as well as the development of cosmological tests of gravity. Einstein's theory of …

Abstract Euclid is a European Space Agency medium-class mission selected for launch in
2020 within the cosmic vision 2015–2025 program. The main goal of Euclid is to understand …

The accelerating expansion of the universe is the most surprising cosmological discovery in
many decades, implying that the universe is dominated by some form of “dark energy” with …

We perform a metastudy of recently published redshift space distortion (RSD)
measurements of the cosmological growth rate, f (z) σ 8 (z). We analyze the latest results …

We explore voids in dark matter and halo fields from simulations of Λ cold dark matter and
Hu–Sawicki f (R) models. In f (R) gravity, dark matter void abundances are greater than that …
