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 …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

We present new measurements of cosmic microwave background (CMB) lensing over 9400
deg 2 of the sky. These lensing measurements are derived from the Atacama Cosmology …

We present cosmological constraints from a gravitational lensing mass map covering 9400
deg 2 reconstructed from measurements of the cosmic microwave background (CMB) made …

We present cosmological results from a combined analysis of galaxy clustering and weak
gravitational lensing, using 1321 deg 2 of griz imaging data from the first year of the Dark …

The Simons Observatory (SO) is a new cosmic microwave background experiment being
built on Cerro Toco in Chile, due to begin observations in the early 2020s. We describe the …

Despite its continued observational successes, there is a persistent (and growing) interest in
extending cosmology beyond the standard model, Λ CDM. This is motivated by a range of …

We present the most significant measurement of the cosmic microwave background (CMB)
lensing potential to date (at a level of 40σ), using temperature and polarization data from the …

We present cosmological parameter constraints based on the final nine-year Wilkinson
Microwave Anisotropy Probe (WMAP) data, in conjunction with a number of additional …

The European Space Agency's Planck satellite, dedicated to studying the early Universe
and its subsequent evolution, was launched 14 May 2009 and has been scanning the …
