BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy
Hannah Übler, 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 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…
Super-Eddington accretion in protogalactic cores
Tommaso Zana, Pedro R. Capelo, Mairo Boresta +6
The presence of massive black holes (BHs) exceeding already at redshift challenges standard models of BH growth. Super-Eddington (SE) accretion has…
JADES reveals a large population of low mass black holes at high redshift
Sophia Geris, Roberto Maiolino, Yuki Isobe +24
JWST has revealed a large population of active galactic nuclei (AGN) in the distant universe, which are challenging our understanding of early massive black hole seeding and growth…
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…
Super-Eddington accretion in high-redshift quasar hosts: Black-hole driven outflows, galaxy quenching, and the nature of little red dots
Giada Quadri, Alessandro Trinca, Alessandro Lupi +2
The advent of the James Webb Space Telescope has revolutionised our understanding of the high-redshift Universe through its detection of bright, massive galaxies up to $z\gtrsim 10…
Pushing JWST to the extremes: search and scrutiny of bright galaxy candidates at z15-30
M. Castellano, A. Fontana, E. Merlin +50
We designed customized Lyman-break color selection techniques to identify galaxy candidates in the redshift ranges and . The selection was pe…
Predicting the number density of heavy seed massive black holes due to an intense Lyman-Werner field
Hannah O'Brennan, John A. Regan, John Brennan +5
The recent detections of a large number of candidate active galactic nuclei at high redshift (i.e. ) has increased speculation that heavy seed massive black hole forma…
BlackTHUNDER -- A non-stellar Balmer break in a black hole-dominated little red dot at
Xihan Ji, Roberto Maiolino, Hannah Übler +34
Recent observations from JWST have revealed an abundant population of active galactic nuclei (AGN) and so-called ``Little Red Dots'' (LRDs) at , many of wh…
