How to raise a supermassive black hole: interpreting early JWST AGN with the AESOPICA simulations
Sophie Koudmani, Jan Scholtz, Anthony J. Taylor +11
The paper uses the AESOPICA suite of cosmological simulations, varying black hole seed masses and accretion physics, to interpret the abundance and apparent overmassiveness of earl…
BlackTHUNDER Reveals a Massive Filament around a Compact AGN at
Giulia Tozzi, Hannah Ãbler, Eleonora Parlanti +27
Despite the growing number of compact active galactic nuclei (AGN) at discovered by JWST, their formation and evolution remain poorly understood. This paper investigates the…
Not all protoclusters host evolved galaxies: Evidence for reduced environmental effects in a lower halo mass protocluster at
Callum Witten, Pascal A. Oesch, Jake S. Bennett +5
The progenitors of present-day galaxy clusters offer crucial insight into how galaxies and large-scale structure co-evolve in the early Universe. We present JWST/NIRCam grism spect…
GA-NIFS: The interplay between feedback and star formation at 3 < z < 9 probed by JWST/NIRSpec IFU
L. Ulivi, M. Perna, S. Arribas +24
The study of starburst- and AGN-driven feedback is fundamental for understanding the processes that shape galaxy growth, quench star formation, and drive the co-evolution of galaxi…
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…
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…
