A King, JP Lasota, M Middleton - New Astronomy Reviews, 2023 - Elsevier
The study of ultraluminous X-ray sources (ULXs) has changed dramatically over the last
decade. In this review we first describe the most important observations of ULXs in various …

The assembly of the first massive black holes

K Inayoshi, E Visbal, Z Haiman - Annual Review of Astronomy …, 2020 - annualreviews.org
The existence of∼ 109M⊙ supermassive black holes (SMBHs) within the first billion years
of the Universe has stimulated numerous ideas for the prompt formation and rapid growth of …

The X–shooter/ALMA Sample of Quasars in the Epoch of Reionization. II. Black Hole Masses, Eddington Ratios, and the Formation of the First Quasars

EP Farina, JT Schindler, F Walter… - The Astrophysical …, 2022 - iopscience.iop.org
We present measurements of black hole masses and Eddington ratios (λ Edd) for a sample
of 38 bright (M 1450<− 24.4 mag) quasars at 5.8≲ z≲ 7.5, derived from Very Large …

First tidal disruption events discovered by SRG/eROSITA: X-ray/optical properties and X-ray luminosity function at z < 0.6

S Sazonov, M Gilfanov, P Medvedev… - Monthly Notices of …, 2021 - academic.oup.com
We present the first sample of tidal disruption events (TDEs) discovered during the SRG all-
sky survey. These 13 events were selected among X-ray transients detected in the 0°< l< …

Ultraluminous X-ray sources

P Kaaret, H Feng, TP Roberts - Annual Review of Astronomy …, 2017 - annualreviews.org
We review observations of ultraluminous X-ray sources (ULXs). X-ray spectroscopic and
timing studies of ULXs suggest a new accretion state distinct from those seen in Galactic …

Constraining the primordial black hole scenario with Bayesian inference and machine learning: the GWTC-2 gravitational wave catalog

KWK Wong, G Franciolini, V De Luca, V Baibhav… - Physical Review D, 2021 - APS
Primordial black holes (PBHs) might be formed in the early Universe and could comprise at
least a fraction of the dark matter. Using the recently released GWTC-2 dataset from the third …

A high black-hole-to-host mass ratio in a lensed AGN in the early Universe

LJ Furtak, I Labbé, A Zitrin, JE Greene, P Dayal… - Nature, 2024 - nature.com
Early JWST observations have uncovered a population of red sources that might represent a
previously overlooked phase of supermassive black hole growth,–. One of the most …

A global three-dimensional radiation magneto-hydrodynamic simulation of super-eddington accretion disks

YF Jiang, JM Stone, SW Davis - The Astrophysical Journal, 2014 - iopscience.iop.org
We study super-Eddington accretion flows onto black holes using a global three-
dimensional radiation magneto-hydrodynamical simulation. We solve the time-dependent …

Rates of stellar tidal disruption as probes of the supermassive black hole mass function

NC Stone, BD Metzger - Monthly Notices of the Royal …, 2016 - academic.oup.com
Rates of stellar tidal disruption events (TDEs) by supermassive black holes (SMBHs) due to
two-body relaxation are calculated using a large galaxy sample (N≈ 200) in order to …

Formation of supermassive black holes

M Volonteri - The Astronomy and Astrophysics Review, 2010 - Springer
Evidence shows that massive black holes reside in most local galaxies. Studies have also
established a number of relations between the MBH mass and properties of the host galaxy …
