Multiphase images of a powerful supernova-driven wind in the early Universe
Rebecca L. Davies, D. B. Fisher, R. Herrera-Camus +38

GA-NIFS and JADES: Confirmation of pristine gas near GN-z11
Hannah Übler, Roberto Maiolino, Pablo G. Pérez-González +32
According to the leading cosmological model, a first generation of stars called Population III (PopIII), condensed almost entirely out of hydrogen and helium, must have initiated t…

GA-NIFS: AGN activity in a Lyα emitter within a triple-AGN system anchored by a passive galaxy at z=3
Michele Perna, Santiago Arribas, Mahmoud Hamed +15
Massive quenched galaxies at z>3 challenge models of early galaxy evolution, as their rapid formation and abrupt quenching require efficient feedback, often linked to active galact…
Undermassive Hosts of AGN from JWST/NIRCam Image Decomposition with CONGRESS, FRESCO, and JADES
Zheng Ma, Eichi Egami, Yongda Zhu +18
In the local Universe, supermassive black hole (SMBH) masses strongly correlate with their host-galaxies' stellar masses (), but galaxies hosting faint AGN recently found by…

Doubling NIRSpec/IFS capability to calibrate the single-epoch black hole mass relation at high redshifts
Eleonora Parlanti, Bartolomeo Trefoloni, Stefano Carniani +6
The recent discovery of a large population of overmassive black holes (BHs) in the early Universe challenges the validity of the BH-host galaxy coevolution framework. However, the…
