This review presents a comprehensive overview of galaxy bias, that is, the statistical relation
between the distribution of galaxies and matter. We focus on large scales where cosmic …

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 cosmological parameter results from the final full-mission Planck measurements
of the cosmic microwave background (CMB) anisotropies, combining information from the …

MontePython is a parameter inference package for cosmology. We present the latest
development of the code over the past couple of years. We explain, in particular, two new …

Axions comprise a broad class of particles that can play a major role in explaining the
unknown aspects of cosmology. They are also well-motivated within high energy physics …

In a six-year program started in 2014 July, the Extended Baryon Oscillation Spectroscopic
Survey (eBOSS) will conduct novel cosmological observations using the BOSS …

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 …

Abstract A flat Friedmann–Robertson–Walker universe dominated by a cosmological
constant (Λ) and cold dark matter (CDM) has been the working model preferred by …

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 …

Ultralight axions (ULAs) with masses in the range 1 0-33 eV≤ ma≤ 1 0-20 eV are motivated
by string theory and might contribute to either the dark-matter or dark-energy densities of the …
