Clustering constraints on super-early galaxy formation scenarios
Antonio Matteri, Andrea Pallottini, Andrea Ferrara
The unexpectedly high abundance of bright, blue, super-early galaxies () has challenged most pre-JWST models of early galaxy formation and motivated a wide range of pro…

Beyond the first galaxies primordial black holes shine
Antonio Matteri, Andrea Ferrara, Andrea Pallottini
The presence of nine candidate galaxies at and discovered by the James Webb Space Telescope in relatively small sky areas, if confirmed, is virtually impossible to re…

Can primordial black holes explain the overabundance of bright super-early galaxies?
Antonio Matteri, Andrea Pallottini, Andrea Ferrara
JWST is detecting an excess of high-redshift (), bright galaxies challenging most theoretical predictions. To address this issue, we investigate the impact of Primordi…
