So far, roughly 40 quasars with redshifts greater than z = 6 have been discovered. Each quasar contains a black hole with a mass of about one billion solar masses (109 ). The existence of such black holes when the Universe was less than one billion years old presents substantial challenges to theories of the formation and growth of black holes and the coevolution of black holes and galaxies. Here we report the discovery of an ultraluminous quasar, SDSS J010013.02+280225.8, at redshift z = 6.30… 

An 800-million-solar-mass black hole in a significantly neutral Universe at a redshift of 7.5

TLDR
Strong evidence of absorption of the spectrum of the quasar redwards of the Lyman α emission line (the Gunn–Peterson damping wing), as would be expected if a significant amount of the hydrogen in the intergalactic medium surrounding J1342 + 0928 is neutral, and a significant fraction of neutral hydrogen is derived, although the exact fraction depends on the modelling.

Discovery of a 12 billion solar mass black hole at redshift 6.3 and its challenge to the black hole/galaxy coevolution at cosmic dawn

Abstract The existence of black holes with masses of about one billion solar masses in quasars at redshifts z > 6 presents significant challenges to theories of the formation and growth of black

A 17-billion-solar-mass black hole in a group galaxy with a diffuse core

TLDR
Observations of the stellar velocity distribution in the galaxy NGC 1600 find that the region of depleted stellar density in the cores of massive elliptical galaxies extends over the same radius as the gravitational sphere of influence of the central black holes, and interpret this as the dynamical imprint of the black holes.

Physical Properties of 15 Quasars at z ≳ 6.5

Quasars are galaxies hosting accreting supermassive black holes; due to their brightness, they are unique probes of the early universe. To date, only a few quasars have been reported at (<800 Myr

Probing Early Supermassive Black Hole Growth and Quasar Evolution with Near-infrared Spectroscopy of 37 Reionization-era Quasars at 6.3 < z ≤ 7.64

We report the results of near-infrared spectroscopic observations of 37 quasars in the redshift range 6.3 < z ≤ 7.64, including 32 quasars at z > 6.5, forming the largest quasar near-infrared

The Discovery of a Highly Accreting, Radio-loud Quasar at z = 6.82

Radio sources at the highest redshifts can provide unique information on the first massive galaxies and black holes, the densest primordial environments, and the epoch of reionization. The number of

Detecting and Characterizing Young Quasars. I. Systemic Redshifts and Proximity Zone Measurements

In a multiwavelength survey of 13 quasars at 5.8 ≲ z ≲ 6.5, which were preselected to be potentially young, we find five objects with extremely small proximity zone sizes that may imply UV-luminous

The recent discovery of the ultraluminous quasar SDSS J010013.02+280225.8 at redshift 6.3 has exacerbated the time compression problem implied by the appearance of supermassive black holes only

A tiny host galaxy for the first giant black hole:z = 7.5 quasar in BlueTides

The most distant known quasar recently discovered by Banados et al. (2018) is at z=7.5 (690 Myr after the Big Bang), at the dawn of galaxy formation. We explore the host galaxy of the brightest

A thirty-four billion solar mass black hole in SMSS J2157–3602, the most luminous known quasar

From near-infrared spectroscopic measurements of the Mg ii emission line doublet, we estimate the black hole (BH) mass of the quasar, SMSS J215728.21–360215.1, as being (3.4 ± 0.6) × 1010 M⊙ and

A luminous quasar at a redshift of z = 7.085

TLDR
Observations of a quasar at a redshift of 7.3 are reported, suggesting that the neutral fraction of the intergalactic medium in front of ULAS J1120+0641 exceeded 0.1.

TLDR
NGC 3842, the brightest galaxy in a cluster at a distance from Earth of 98 megaparsecs, has a central black hole with a mass of 9.7 billion solar masses, and that a black hole of comparable or greater mass is present in NGC 4889, the bright galaxy in the Coma cluster.

The cosmological evolution of quasar black hole masses

Black Hole Masses and Enrichment of z ~ 6 SDSS Quasars

We present sensitive near-infrared spectroscopic observations for a sample of five z ~ 6 quasars. These quasars are among the most distant, currently known quasars in the universe. The spectra have

TLDR
A luminous unresolved object with a featureless optical spectrum redward of the Lyalpha forest region, discovered from Sloan Digital Sky Survey commissioning data, is either the most distant BL Lac object known to date, with very weak radio emission, or a new type of unbeamed quasar, whose broad emission line region is very weak or absent.
