We present a search for and characterization of ionized outflows in 15 star-forming systems at with no evidence of Active Galactic Nuclei (AGN), observed with JWST/NIRSp…
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…
BlackTHUNDER: Evidence of three massive black holes in a z~5 galaxy

Net-zero gas inflow: Measurement of the gas consumption history of a massive quiescent galaxy
Jan Scholtz, Francesco D'Eugenio, Roberto Maiolino +23
JWST is discovering increasing numbers of quiescent galaxies 1--2 billion years after the Big Bang, whose redshift, high mass, and old stellar ages indicate that their formation an…
