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 …

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 …

ABSTRACT The Wilkinson Microwave Anisotropy Probe (WMAP) 5-year data provide
stringent limits on deviations from the minimal, six-parameter Λ cold dark matter model. We …

We present cosmological results from the final galaxy clustering data set of the Baryon
Oscillation Spectroscopic Survey, part of the Sloan Digital Sky Survey III. Our combined …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

We present results from 13 cosmological simulations that explore the parameter space of the
'Evolution and Assembly of GaLaxies and their Environments'(EAGLE) simulation project …

We derive constraints on cosmological parameters and tests of dark energy models from the
combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave …

We present the all-sky Planck catalogue of Sunyaev-Zeldovich (SZ) sources detected from
the 29 month full-mission data. The catalogue (PSZ2) is the largest SZ-selected sample of …

We describe redMaPPer, a new red sequence cluster finder specifically designed to make
optimal use of ongoing and near-future large photometric surveys. The algorithm has …

Formation of galaxy clusters corresponds to the collapse of the largest gravitationally bound
overdensities in the initial density field and is accompanied by the most energetic …
