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 review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

Context. We present the third data release of the European Space Agency's Gaia mission,
Gaia DR3. This release includes a large variety of new data products, notably a much …

This paper documents the seventeenth data release (DR17) from the Sloan Digital Sky
Surveys; the fifth and final release from the fourth phase (SDSS-IV). DR17 contains the …

The goal of the Dark Energy Spectroscopic Instrument (DESI) is to determine the nature of
dark energy through the most precise measurement of the expansion history of the universe …

We present cosmological results from the measurement of baryon acoustic oscillations
(BAO) in galaxy, quasar and Lyman-$\alpha $ forest tracers from the first year of …

Measurement of the distances to nearby galaxies has improved rapidly in recent decades.
The ever-present challenge is to reduce systematic effects, especially as greater distances …

Context. Data from the Gaia satellite are revolutionising our understanding of the Milky Way.
With every new data release, there is a need to update the census of open clusters. Aims …

Stellar distances constitute a foundational pillar of astrophysics. The publication of 1.47
billion stellar parallaxes from Gaia is a major contribution to this. Despite Gaia's precision …

Context. Gaia Early Data Release 3 (Gaia EDR3) contains results for 1.812 billion sources in
the magnitude range G= 3–21 based on observations collected by the European Space …
