BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Ãbler, Giovanni Mazzolari, Roberto Maiolino +41
We present observational evidence of three massive, accreting black holes (BHs) in the z=5.0167 galaxy J0148-4214 from JWST/NIRSpec-IFU spectroscopy. The BHs are revealed through b…
A black hole in a near-pristine galaxy 700 million years after the Big Bang
Roberto Maiolino, Hannah Uebler, Francesco D'Eugenio +36
The recent discovery of a large number of massive black holes within the first two billion years after the Big Bang, as well as their peculiar properties, have been largely unexpec…
The Cliff: A Metal-Poor Little Red Dot Hosting an Overmassive Black Hole at
Lucy R. Ivey, Francesco D'Eugenio, Roberto Maiolino +19
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei…
A Novel Formation Channel for Supermassive Black Hole Binaries in the Early Universe via Primordial Black Holes
Saiyang Zhang, Boyuan Liu, Volker Bromm
We present a novel formation channel for supermassive black hole (SMBH) binaries in the early Universe, driven by primordial black holes (PBHs). Using high-resolution hydrodynamica…
A direct black hole mass measurement in a Little Red Dot at the Epoch of Reionization
Ignas Juodžbalis, Cosimo Marconcini, Francesco D'Eugenio +37
Recent discoveries of faint active galactic nuclei (AGN) at the redshift frontier have revealed a plethora of broad \Halpha emitters with optically red continua, named Little Red D…
