Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …

We review results from cosmic X-ray surveys of active galactic nuclei (AGNs) over the past
≈ 15≈ 15 years that have dramatically improved our understanding of growing …

We report on the discovery of two low-luminosity, broad-line active galactic nuclei (AGNs) at
z> 5 identified using JWST NIRSpec spectroscopy from the Cosmic Evolution Early Release …

Using a compilation of 25 studies from the literature, we investigate the evolution of the star-
forming galaxy (SFG) main sequence (MS) in stellar mass and star formation rate (SFR) out …

The Low Frequency Array (LOFAR) is an ideal instrument to conduct deep extragalactic
surveys. It has a large field of view and is sensitive to large-scale and compact emission. It …

We develop a model for the cosmological role of mergers in the evolution of starbursts,
quasars, and spheroidal galaxies. By combining theoretically well-constrained halo and …

ABSTRACT The Wide-field Infrared Survey Explorer (WISE) is an extremely capable and
efficient black hole finder. We present a simple mid-infrared color criterion, W1− W2⩾ 0.8 …

We present initial results of an ESO-VLT large programme (AMAZE) aimed at determining
the evolution of the mass-metallicity relation at z> 3 by means of deep near-IR spectroscopy …

We have carried out a survey of the north and south ecliptic poles, EP-N and EP-S,
respectively, with the Spitzer Space Telescope and the Wide-field Infrared Survey Explorer …

We present the SEDs of a hard X-ray selected sample containing 136 sources with F 2-10
keV> 10-14 erg cm-2 s-1; 132 are AGNs. The sources are detected in a 1 deg 2 area of the …
