Constraints on Dark Matter Models from Supermassive Black Hole Evolution
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
A semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) within the CDM paradigm has been shown to yield stellar mass-BH mass relations that re…
Starlight from JWST: Implications for star formation and dark matter models
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
We confront the star formation rate in different dark matter (DM) models with UV luminosity data from JWST up to and legacy data from HST. We find that a transition fro…
What is the origin of the JWST SMBHs?
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
We present a new semi-analytical model for the evolution of galaxies and supermassive black holes (SMBHs) that is based on the extended Press-Schechter formalism and phenomenologic…
Consistency of JWST Black Hole Observations with NANOGrav Gravitational Wave Measurements
John Ellis, Malcolm Fairbairn, Gert Hütsi +3
JWST observations have opened a new chapter in studies of supermassive black holes (SMBHs), stimulating discussion of two puzzles: the abundance of SMBHs in the early Universe and…
Probing supermassive black hole seed scenarios with gravitational wave measurements
John Ellis, Malcolm Fairbairn, Juan Urrutia +1
The process whereby the supermassive black holes populating the centers of galaxies have been assembled remains to be established, with the relative importance of seeds provided by…
