Growth of Light Seed Black Holes in the Early Universe

Daxal H. Mehta, John A. Regan, Lewis Prole

Observations from the James Webb Space Telescope (JWST) have uncovered supermassive black holes (SMBHs) with masses exceeding at redshifts , posing…

Beyond No Tension: JWST z > 10 Galaxies Push Simulations to the Limit

Joe McCaffrey, Samantha Hardin, John H. Wise +1

JWST has identified some of the Universe's earliest galaxies, repeatedly pushing the frontier to ever higher redshifts and stellar masses. The presence of such extreme galaxies at…

Primordial black holes in cosmological simulations: growth prospects for supermassive black holes

Lewis R. Prole, John A. Regan, Daxal Mehta +2

It has long been suggested that a fraction of the dark matter in the Universe could exist in the form of primordial black holes (PBHs) that have existed since the radiation dominat…

Predicting the number density of heavy seed massive black holes due to an intense Lyman-Werner field

Hannah O'Brennan, John A. Regan, John Brennan +5

The recent detections of a large number of candidate active galactic nuclei at high redshift (i.e. ) has increased speculation that heavy seed massive black hole forma…

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…
