Ultraviolet diversity of Little Red Dots as a probe for direct-collapse black hole ages
Elia Cenci, Melanie Habouzit, Dale D. Kocevski
Little Red Dots (LRDs) uncovered by the James Webb Space Telescope have been proposed as candidate galaxies hosting embedded accreting direct-collapse black holes (DCBHs), yet the…
The Nature of Post-Starburst Galaxies: Real Deal or Masquerading Impostors?
Elia Cenci, Robert Feldmann, Sarah Wellons +7
Post-starburst galaxies (PSBs) are a population of galaxies with spectral and photometric features indicative of rapid quenching following a recent starburst. The origin and nature…
A novel sub-grid model for super-Eddington accretion of spinning black holes in galaxy-scale simulations
Wei-Bo Kao, Pedro R. Capelo, Elia Cenci +3
Super-Eddington accretion has been proposed to explain the existence of black holes (BHs) with masses exceeding a billion solar masses within the first billion years after the Big…
Igniting galaxy formation in the post-reionization universe
Jorge Moreno, Coral Wheeler, Francisco J. Mercado +9
It is widely believed that the ultraviolet background produced during the epoch of reionization conspires against the formation of low-mass galaxies. Indeed, this mechanism is ofte…
SQuIGGE: Buried star formation cannot explain the rapidly fading CO(2-1) luminosity in massive, post-starburst galaxies
David J. Setton, Justin S. Spilker, Rachel Bezanson +12
Observational and theoretical studies have long held that rapid gas consumption in starbursts is responsible for the formation of quiescent galaxies. However, studies of recently q…
Little Red Dots as Direct-collapse Black Hole Nurseries
Elia Cenci, Melanie Habouzit
The James Webb Space Telescope recently uncovered a population of massive black holes (BHs) in the first billion years after the Big Bang. Among these high-redshift BH candidates,…
