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…
REBELS-25: Discovery of a dynamically cold disc galaxy at z = 7.31
Lucie E. Rowland, Jacqueline Hodge, Rychard Bouwens +21
We present high resolution (" = 710 pc) ALMA [CII] 158m and dust continuum follow-up observations of REBELS-25, a [CII]-luminous ($L_{\mathrm{[CII]}}=(1.7\pm0.2)\times…
An optically-dark merging system at z~6 detected by JWST
Giulia Rodighiero, Andrea Enia, Laura Bisigello +16
Near- to mid-Infrared observations (from Spitzer and JWST) have revealed a hidden population of galaxies at redshift z=3-6, called optically-dark objects, which are believed to be…
Is GN-z11 powered by a super-Eddington massive black hole?
Maulik Bhatt, Simona Gallerani, Andrea Ferrara +6
Observations of quasars powered by supermassive black holes (SMBHs; ) challenge our current understanding of early black hole (BH) f…
