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…
How can we finally see the first light? Status and perspective in the search for Population III stars
Alessandra Venditti, Daniel Schaerer, Erik Zackrisson +26
Finding the first (Population III or Pop III) stars is one of the fundamental quests of astronomy, aiming to deliver the missing link in how stars form at early cosmic times. Yet t…
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…
First-star imprints in a metal-poor galaxy overdensity near the end of reionization
Zihao Li, Koki Kakiichi, Lise Christensen +24
The first generation of stars, known as Population III (Pop III), formed from primordial gas consisting solely of hydrogen and helium and is believed to have emerged only a few hun…
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…
JADES: the chemical enrichment pattern of distant galaxies -- enhancement, silicon depletion, and iron enhancement
Yuki Isobe, Roberto Maiolino, Xihan Ji +26
We present gas-phase abundances of carbon (C), -elements (O, Ne, Si, and Ar) and iron (Fe) obtained from stacked spectra of high- star-forming galaxies with the deep Near Inf…
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)…
Hidden Population III Descendants in Ultra-Faint Dwarf Galaxies
Martina Rossi, Stefania Salvadori, Ása Skúladóttir +2
The elusive properties of the first (Pop III) stars can be indirectly unveiled by uncovering their true descendants. To this aim, we exploit our data-calibrated model for the best-…
On the Pair-Instability Supernova origin of J1010+2358
Ása Skúladóttir, Ioanna Koutsouridou, Irene Vanni +4
The first (Pop III) stars formed only out of H and He and were likely more massive than present-day stars. Massive Pop III stars in the range 140-260 M are predicted to end…
Chemical Diagnostics to Unveil Environments Enriched by First Stars
Irene Vanni, Stefania Salvadori, Valentina D'Odorico +2
Unveiling the chemical fingerprints of the first (Pop III) stars is crucial for indirectly studying their properties and probing their massive nature. In particular, very massive P…
True Pair-instability Supernova Descendant: Implications for the First Stars' Mass Distribution
Ioanna Koutsouridou, Stefania Salvadori, Ása Skúladóttir
The initial mass function (IMF) of the first Pop III stars remains a persistent mystery. Their predicted massive nature implies the existence of stars exploding as pair-instability…
Tracing Pop III supernovae with extreme energies through the Sculptor dwarf spheroidal galaxy
Ása Skúladóttir, Irene Vanni, Stefania Salvadori +1
The Sculptor dwarf spheroidal galaxy is old and metal-poor, making it ideal to study the earliest chemical enrichment in the Local Group. We followed up the most metal-poor star kn…
On the dearth of C-enhanced metal-poor stars in the Galactic bulge
Giulia Pagnini, Stefania Salvadori, Martina Rossi +3
The chemical fingerprints of the first stars are retained within the photospheres of ancient unevolved metal-poor stars. A significant fraction of these stellar fossils is represen…
