Hydrogen Lyman-α (Lyα) emission has been one of the major observational probes for the
high-redshift Universe since the first discoveries of high-z Lyα-emitting galaxies in the late …

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 …

The LOFAR Two-metre Sky Survey (LoTSS) is a deep 120–168 MHz imaging survey that will
eventually cover the entire northern sky. Each of the 3170 pointings will be observed for 8 h …

Line-intensity mapping (LIM) is an emerging approach to survey the Universe, using
relatively low-aperture instruments to scan large portions of the sky and collect the total …

Abstract The Hobby–Eberly Telescope (HET) Dark Energy Experiment (HETDEX) is
undertaking a blind wide-field low-resolution spectroscopic survey of 540 deg 2 of sky to …

We measure the large-scale cross-correlation of quasars with the Lyα forest absorption,
using over 164,000 quasars from Data Release 11 of the SDSS-III Baryon Oscillation …

Abstract The Dark Energy Spectroscopic Instrument (DESI) Survey has obtained a set of
spectroscopic measurements of galaxies to validate the final survey design and target …

Abstract The Galaxy And Mass Assembly (GAMA) survey is one of the largest contemporary
spectroscopic surveys of low redshift galaxies. Covering an area of∼ 286 deg2 (split among …

We present the first application to density field reconstruction to a galaxy survey to undo the
smoothing of the baryon acoustic oscillation (BAO) feature due to non-linear gravitational …

Abstract The spectroscopic Sloan Digital Sky Survey (SDSS) Data Release 7 (DR7) galaxy
sample represents the final set of galaxies observed using the original SDSS target …
