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…
511 keV Galactic Photons from a Dark Matter Spike
Pedro De la Torre Luque, Shyam Balaji, Malcolm Fairbairn +2
We propose that a dark matter (DM) spike around the Galactic Center's (GC) supermassive black hole, Sgr A*, could account for most of the bulge's measured 511 keV line intensity wh…
