One century after its formulation, Einstein's general relativity (GR) has made remarkable
predictions and turned out to be compatible with all experimental tests. Most of these tests …

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 The DESI Legacy Imaging Surveys (http://legacysurvey. org/) are a combination of
three public projects (the Dark Energy Camera Legacy Survey, the Bei**g–Arizona Sky …

DESI (Dark Energy Spectroscopic Instrument) is a Stage IV ground-based dark energy
experiment that will study baryon acoustic oscillations (BAO) and the growth of structure …

Understanding the reason for the observed accelerated expansion of the Universe
represents one of the fundamental open questions in physics. In cosmology, a classification …

Long range scalar fields with a coupling to matter appear to violate known bounds on
gravitation in the solar system and the laboratory. This is evaded thanks to screening …

We present high signal-to-noise galaxy–galaxy lensing measurements of the Baryon
Oscillation Spectroscopic Survey constant mass (CMASS) sample using 250 deg2 of weak …

We perform the first fit to the anisotropic clustering of Sloan Digital Sky Survey III CMASS
data release 10 galaxies on scales of∼ 0.8–32 h− 1 Mpc. A standard halo occupation …

The Novel Probes Project, an initiative to advance the field of astrophysical tests of the dark
sector by creating a forum that connects observers and theorists, is introduced. This review …

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 …
