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 …

In this paper, we provide updated constraints on the bolometric quasar luminosity function
(QLF) from z= 0 to z= 7. The constraints are based on an observational compilation that …

Context. Feedback from accreting supermassive black holes (SMBHs) is often identified as
the main mechanism responsible for regulating star formation in active galactic nucleus …

ABSTRACT The Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey
(CANDELS) is designed to document the first third of galactic evolution, over the …

Determinations of the ultraviolet (UV) luminosity function of active galactic nuclei (AGN) at
high redshifts are important for constraining the AGN contribution to reionization and …

We present new measurements of the evolution of the X-ray luminosity functions (XLFs) of
unabsorbed and absorbed active galactic nuclei (AGNs) out to z∼ 5. We construct samples …

In this study, we present a detailed, statistical analysis of black hole growth and the evolution
of active galactic nuclei (AGN) using cosmological hydrodynamic simulations run down to z …

We aim to constrain the evolution of active galactic nuclei (AGNs) as a function of
obscuration using an X-ray-selected sample of∼ 2000 AGNs from a multi-tiered survey …

We present the most up to date X-ray luminosity function (XLF) and absorption function of
active galactic nuclei (AGNs) over the redshift range from 0 to 5, utilizing the largest, highly …

We present new observational determinations of the evolution of the 2–10 keV X-ray
luminosity function (XLF) of active galactic nuclei (AGN). We utilize data from a number of …
