A Selection Aware View of Black Hole-Galaxy Coevolution at High Redshift
Francesco Ziparo, Stefano Carniani, Simona Gallerani +1
The large population of broad-line Active Galactic Nuclei (AGN) observed with the James Webb Space Telescope (JWST) at opens a new window onto the black hole-galaxy c…
Primordial black holes as supermassive black holes seeds
Francesco Ziparo, Simona Gallerani, Andrea Ferrara
The presence of supermassive black holes (SMBHs, ) in the first cosmic Gyr () challenges current models of BH formation and evoluti…
Primordial Black Holes as Near Infrared Background sources
D. Manzoni, F. Ziparo, S. Gallerani +1
The near infrared background (NIRB) is the collective light from unresolved sources observed in the band 1-10 m. The measured NIRB angular power spectrum on angular scales $θ\gt…
Cosmic radiation backgrounds from primordial black holes
Francesco Ziparo, Simona Gallerani, Andrea Ferrara +1
Recent measurements of the cosmic X-ray and radio backgrounds (CXB/CRB, respectively) obtained with Chandra and ARCADE2 report signals in excess of those expected from known source…
Blue Monsters. Why are JWST super-early, massive galaxies so blue?
Francesco Ziparo, Andrea Ferrara, Laura Sommovigo +1
The recent JWST tentative discovery of a population of super-early (redshift ), relatively massive (stellar mass ) and evolved (metallicity $Z \app…
Gemini Observations of Galaxies in Rich Early Environments (GOGREEN) I: Survey Description
Michael L. Balogh, David G. Gilbank, Adam Muzzin +29
We describe a new Large Program in progress on the Gemini North and South telescopes: Gemini Observations of Galaxies in Rich Early Environments (GOGREEN). This is an imaging and d…
