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…
An (in)complete NIRSpec census of Balmer absorption in Type 1 AGN -- radiation-driven outflows in little red dots, quasars and variable stars
Ignas Juodžbalis, Xihan Ji, Francesco D'Eugenio +17
A notable achievement of the first generation of JWST surveys was the discovery of an abundance of faint high-redshift () broad-line active galactic nuclei (AGN) in the $L_{…
GA-NIFS: high prevalence of dusty and metal-enriched outflows in massive and luminous star-forming galaxies at
B. RodrÃguez Del Pino, S. Arribas, M. Perna +16
The paper investigates ionized outflows in massive, luminous star-forming galaxies at redshifts 3–9 using JWST/NIRSpec IFU data, finding that the outflows are dusty and metal‑enric…
GA-NIFS: Powerful and frequent outflows in moderate-luminosity active galactic nuclei at
Giacomo Venturi, Stefano Carniani, Elena Bertola +18
The period between z ~ 3-6, a key transformational phase in galaxy evolution preceding 'cosmic noon' (z ~ 1-3), is very poorly explored in terms of feedback from AGN acting through…
A stellar bar hidden in an extreme gas-rich disk galaxy at z=4.055
Leindert A. Boogaard, Luca Costantin, Thor Tepper-GarcÃa +14
The classical picture for the formation of stellar bars -- key dynamical drivers of the evolution of galaxies -- is through secular evolution of instability in gas poor, stellar-do…
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…
