Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

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 Sloan Digital Sky Surveys (SDSS) have been almost continuously observing the skies
for over 20 yr, since the project began with a first phase in 1998 (SDSS-I; York et al. 2000) …

We measure the anisotropic clustering of the quasar sample from Data Release 16 (DR16)
of the Sloan Digital Sky Survey IV extended Baryon Oscillation Spectroscopic Survey …

We present the final Sloan Digital Sky Survey IV (SDSS-IV) quasar catalog from Data
Release 16 of the extended Baryon Oscillation Spectroscopic Survey (eBOSS). This catalog …

We present a tomographic cosmic shear analysis of the Kilo-Degree Survey (KiDS)
combined with the VISTA Kilo-Degree Infrared Galaxy Survey. This is the first time that a full …

The study of the dynamical evolution of massive black hole pairs in mergers is crucial in the
context of a hierarchical galaxy formation scenario. The timescales for the formation and the …

We present measurements of the Baryon Acoustic Oscillation (BAO) scale in redshift-space
using the clustering of quasars. We consider a sample of 147 000 quasars from the …

ABSTRACT The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure
the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger …

We present redshift distribution estimates of galaxies selected from the fourth data release of
the Kilo-Degree Survey over an area of∼ 1000 deg 2 (KiDS-1000). These redshift …
