Intermediate-mass black holes
JE Greene, J Strader, LC Ho - Annual Review of Astronomy and …, 2020 - annualreviews.org
We describe ongoing searches for intermediate-mass black holes with M BH≈ 10–105 M⊙.
We review a range of search mechanisms, both dynamical and those that rely on accretion …

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 …

UNCOVER: The Growth of the First Massive Black Holes from JWST/NIRSpec—Spectroscopic Redshift Confirmation of an X-Ray Luminous AGN at z= 10.1
Abstract The James Webb Space Telescope is now detecting early black holes (BHs) as
they transition from" seeds" to supermassive BHs. Recently, Bogdan et al. reported the …

Evidence for heavy-seed origin of early supermassive black holes from a z ≈ 10 X-ray quasar
Observations of quasars reveal that many supermassive black holes (BHs) were in place
less than 700 Myr after the Big Bang. However, the origin of the first BHs remains a mystery …

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 …

Cosmic microwave background bounds on primordial black holes including dark matter halo accretion
Even if massive (10 M⊙≲ M≲ 10 4 M⊙) primordial black holes (PBHs) can only account for
a small fraction of the dark matter (DM) in the universe, they may still be responsible for a …

First Detection of an Overmassive Black Hole Galaxy UHZ1: Evidence for Heavy Black Hole Seed Formation from Direct Collapse
The recent Chandra-JWST discovery of a quasar in the z≈ 10.1 galaxy UHZ1 reveals that
accreting supermassive black holes were already in place 470 million years after the Big …
