A number of challenges to the standard Λ CDM model have been emerging during the past
few years as the accuracy of cosmological observations improves. In this review we discuss …

We systematically review some standard issues and also the latest developments of
modified gravity in cosmology, emphasizing on inflation, bouncing cosmology and late-time …

We present the cosmological implications from final measurements of clustering using
galaxies, quasars, and Ly α forests from the completed Sloan Digital Sky Survey (SDSS) …

We report on the implications for cosmic inflation of the 2018 release of the Planck cosmic
microwave background (CMB) anisotropy measurements. The results are fully consistent …

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 …

We present evidence for a suppressed growth rate of large-scale structure during the dark-
energy-dominated era. Modeling the growth rate of perturbations with the “growth index” γ …

We present cosmological parameter results from the final full-mission Planck measurements
of the CMB anisotropies. We find good consistency with the standard spatially-flat 6 …

We present a catalog of galaxy clusters selected via their Sunyaev–Zel'dovich (SZ) effect
signature from 2500 deg 2 of South Pole Telescope (SPT) data. This work represents the …

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 …
