GA-NIFS view of LAP1: Assembly of Pop~III stellar clusters during EoR

J. Scholtz, R. Maiolino, S. Carniani +28

Lensed and Pristine 1 (LAP1) is one of the most promising candidates for the detection of so-called Pop~III stars at . In this work, we present new high-spectral-resoluti…

CRIMSONS: An Online Tool for Modeling Chemical Enrichment with Stochastic IMF Sampling

Martina Rossi, Lapo Querci, Stefano Ciabattini +14

Chemical enrichment is a universal process shaped by several interconnected factors, including stellar feedback, the nature of chemical polluters, and the underlying distribution o…

Chemical signatures from the first stars embedded in metal-poor gas in galaxies at cosmic dawn

Clara L. Pollock, Kasper E. Heintz, Elka Rusta +15

The first generation of stars formed from pristine, neutral hydrogen gas. The most massive of these exploded as supernovae within a few million years of their birth, producing the…

NEFERTITI: Linking early galaxy formation to the assembly of the Milky Way

Ioanna Koutsouridou, Stefania Salvadori, Ása Skúladóttir +5

We use a new implementation of the NEFERTITI galaxy formation model, coupled to high-resolution Caterpillar dark-matter simulations of Milky Way (MW) analogues, to connec…

The Pristine HeII Emitter near GN-z11: Constraining the Mass Distribution of the First Stars

Elka Rusta, Stefania Salvadori, Roberto Maiolino +6

The properties of the first metal-free stars remain largely unknown, and so far, the only data-driven constraints on their mass distribution (IMF) come from near-field cosmology. H…

The search for Population III: Confirmation of a HeII emitter with no metal lines at z=10.6

Roberto Maiolino, Hannah Übler, 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, conf…

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…

Metal-polluted Population III galaxies and How to Find Them

Elka Rusta, Stefania Salvadori, Viola Gelli +4

Observing Population III (hereafter PopIII) galaxies, the hosts of first-generation stars, remains challenging even with the JWST. The current few candidates have been identified t…

Linking high-z and low-z: Are We Observing the Progenitors of the Milky Way with JWST?

Elka Rusta, Stefania Salvadori, Viola Gelli +2

The recent JWST observation of the Firefly Sparkle at offers a unique opportunity to link the high- and the low- Universe. Indeed, the claim of it being a Milky Way (MW)…
