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 …

An array of large observational programs using ground-based and space-borne telescopes
is planned in the next decade. The forthcoming wide-field sky surveys are expected to …

We present a joint cosmological analysis of weak gravitational lensing observations from the
Kilo-Degree Survey (KiDS-1000), with redshift-space galaxy clustering observations from …

We present cosmological constraints from a cosmic shear analysis of the fourth data release
of the Kilo-Degree Survey (KiDS-1000), which doubles the survey area with nine-band …

Context. The eROSITA X-ray telescope on board the Spectrum-Poentgen-Gamma (SPG)
observatory combines a large field of view and a large collecting area in the energy range …

ABSTRACT We introduce the Virgo Consortium's FLAMINGO suite of hydrodynamical
simulations for cosmology and galaxy cluster physics. To ensure the simulations are …

The Dark Energy Spectroscopic Instrument (DESI) completed its 5 month Survey Validation
in 2021 May. Spectra of stellar and extragalactic targets from Survey Validation constitute …

Abstract We describe the Dark Energy Survey (DES) photometric data set assembled from
the first three years of science operations to support DES Year 3 cosmologic analyses, and …

We present a joint cosmic shear analysis of the Dark Energy Survey (DES Y3) and the Kilo-
Degree Survey (KiDS-1000) in a collaborative effort between the two survey teams. We find …

We present weak lensing shear catalogues from the fourth data release of the Kilo-Degree
Survey, KiDS-1000, spanning 1006 square degrees of deep and high-resolution imaging …
