Hawking Radiation from non-evaporating primordial black holes cannot enable the formation of direct collapse black holes
Jonathan Regan, Marios Kalomenopoulos, Kelly Kosmo O'Neil
The formation of supermassive black holes (SMBHs) in the early Universe is a subject of significant debate. In this study, we examine whether non-evaporating primordial black holes…
Halo Mergers Enhance the Growth of Massive Black Hole Seeds
Lewis R. Prole, John A. Regan, Daniel J. Whalen +2
High redshift observations of 10 M supermassive black holes (SMBHs) at and `Little Red Dots' that may host overmassive black holes at suggests the exist…
A Heavy Seed Black Hole Mass Function at High Redshift -- Prospects for LISA
Joe McCaffrey, John Regan, Britton Smith +3
The advent of new and near-future observatories probing the earliest epochs of the Universe has opened the opportunity to investigate the formation and growth of the first massive…
Growth of Light-Seed Black Holes in Gas-Rich Galaxies at High Redshift
Daxal Mehta, John A. Regan, Lewis Prole
Recent observations by the James Webb Space Telescope confirm the existence of massive black holes ( ) beyond the redshift of . However, their formatio…
Halo mass functions at high redshift
Hannah O'Brennan, John A. Regan, Chris Power +3
Recent JWST observations of very early galaxies, at , have led to claims that tension exists between the sizes and luminosities of high-redshift galaxies and wha…
