Hard X-ray (≥ 10 keV) observations of active galactic nuclei (AGNs) can shed light on some
of the most obscured episodes of accretion onto supermassive black holes. The 70-month …

To provide the census of the sources contributing to the X-ray background peak above 10
keV, Nuclear Spectroscopic Telescope Array (NuSTAR) is performing extragalactic surveys …

The focusing optics of NuSTAR have enabled high signal-to-noise ratio spectra to be
obtained from many X-ray bright active galactic nuclei (AGN) and galactic black hole …

Heavily obscured accretion is believed to represent an important stage in the growth of
supermassive black holes and to play an important role in shaping the observed spectrum of …

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 …

As matter accretes onto the central supermassive black holes in active galactic nuclei
(AGNs), X-rays are emitted. We present a population synthesis model that accounts for the …

We present an updated mid-infrared (MIR) versus X-ray correlation for the local active
galactic nuclei (AGN) population based on the high angular resolution 12 and 18μm …

Abstract The Chandra Deep Fields (CDFs), being a major thrust among extragalactic X-ray
surveys and complemented effectively by multiwavelength observations, have critically …

The bulk of the X-ray emission in active galactic nuclei (AGNs) is produced very close to the
accreting supermassive black hole (SMBH), in a corona of hot electrons which up scatters …
