Charting the expansion of the Universe from z0 to z14 with HII galaxies
R. Chávez, R. Terlevich, A. L. González-Morán +14
The authors construct an updated Hubble diagram using 243 giant H II regions and H II galaxies from redshift 0 to ~14, applying the L(Hβ)–σ relation to derive cosmological paramete…
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…
The search for Population III: Confirmation of a HeII emitter with no metal lines at z=10.6
Roberto Maiolino, Hannah Ãbler, Michele Perna +49
We report the confirmation of a HeII1640 emitter located at 3 pkpc from the galaxy GN-z11, at z=10.6. The detection, based on JWST NIRSpec-IFU high-resolution spectroscopy, con…
GA-NIFS and JADES: Confirmation of pristine gas near GN-z11
Hannah Ãbler, 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: Dissecting The Alchemised: JWST reveals turbulent metal-poor gas fuelling a co-spatial starburst in a complex system at
Robert G. Pascalau, Francesco D'Eugenio, Roberto Maiolino +26
Recent observations revealed that distant galaxies have bursty star formation histories, regulated by stellar or active galactic nuclei (AGN) feedback and gas inflows. According to…
