Quasars and the intergalactic medium at cosmic dawn
Quasars at cosmic dawn provide powerful probes of the formation and growth of the earliest
supermassive black holes (SMBHs) in the Universe, their connections to galaxy and …

Obscured active galactic nuclei
Active galactic nuclei (AGN) are powered by the accretion of material onto a supermassive
black hole (SMBH) and are among the most luminous objects in the Universe. However, the …

A small and vigorous black hole in the early Universe
Several theories have been proposed to describe the formation of black hole seeds in the
early Universe and to explain the emergence of very massive black holes observed in the …

Hidden little monsters: spectroscopic identification of low-mass, broad-line AGNs at z> 5 with CEERS
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 …

A JWST/NIRSpec first census of broad-line AGNs at z= 4–7: detection of 10 faint AGNs with M BH∼ 106–108 M⊙ and their host galaxy properties
We present the first statistical sample of faint type 1 AGNs at z> 4 identified by
JWST/NIRSpec deep spectroscopy. Among the 185 galaxies at z spec= 3.8–8.9 confirmed …

UNCOVER spectroscopy confirms the surprising ubiquity of active galactic nuclei in red sources at z> 5
Abstract The James Webb Space Telescope is revealing a new population of dust-reddened
broad-line active galactic nuclei (AGN) at redshifts z≳ 5. Here we present deep …

UNCOVER: A NIRSpec Identification of a Broad-line AGN at z= 8.50
Deep observations with the James Webb Space Telescope (JWST) have revealed an
emerging population of red pointlike sources that could provide a link between the …

A CEERS discovery of an accreting supermassive black hole 570 Myr after the Big Bang: identifying a progenitor of massive z> 6 quasars
We report the discovery of an accreting supermassive black hole at z= 8.679. This galaxy,
denoted here as CEERS_1019, was previously discovered as a Lyα-break galaxy by …

A census of photometrically selected little red dots at 4< z< 9 in JWST blank fields
Abstract Observations with the James Webb Space Telescope (JWST) have uncovered
numerous faint active galactic nuclei (AGN) at z∼ 5 and beyond. These objects are key to …
