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…
The Rise and Fall of Acoustic Oscillations at Cosmic Dawn
Hector Afonso G. Cruz, Gabriele Montefalcone, Julian B. Muñoz +2
Cosmic dawn 21-cm observations will extend standard-ruler cosmology into the first billion years, unlocking epochs inaccessible by the cosmic microwave background and large-scale s…
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…
Resolving galaxy formation in the early Universe with BonFIRE and CampFIRE
Jenna Samuel, Michael Boylan-Kolchin, Robert Feldmann +16
The abundance and rapid growth of galaxies at cosmic dawn revealed by the James Webb Space Telescope challenges models of galaxy formation, motivating new simulations to uncover th…
Metal Mayhem at z~7-10: Diversity and Evolution of Gas-Phase Metallicity Gradients
Maria Koller, Roberto Maiolino, Hannah Übler +16
We present a JWST/NIRSpec Integral Field Unit (IFU) study of metallicity gradients in seven low-metallicity systems at . The main sample spans stellar masses of $\rm \lo…
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…
Catching the Nebular Needle in a Polluted Haystack: Line-emission Signatures from Population III-forming Pockets around Massive Galaxies at the End of Reionization
Alessandra Venditti, Luca Graziani, Raffaella Schneider +10
Finding the first generation of (Population III or Pop III) stars is one of the most ambitious and exciting challenges of astrophysics. JWST opened concrete prospects for their det…
How Massive Can a Population III Starburst Be? Simulating the First Galaxies with High Lyman-Werner Background
Tae Bong Jeong, Alessandra Venditti, Volker Bromm +4
Observing the first generation of Population~III (Pop~III) stars is one of the most demanding challenges in astronomy. Indeed, Pop~III stars are expected to predominantly form with…
Relatively Fast and Reasonably Furious: Evidence for Increased Burstiness in Smaller Halos at Cosmic Dawn
Julian B. Muñoz, John Chisholm, Guochao Sun +7
We introduce an effective framework to model star-formation burstiness and use it to jointly fit galaxy UV luminosity functions (UVLFs), clustering, and H/UV ratios, providing t…
Hunting for the First Explosions at the High-Redshift Frontier
Junehyoung Jeon, Volker Bromm, Alessandra Venditti +2
The James Webb Space Telescope (JWST) has spectroscopically confirmed galaxies up to , 300 Myr after the Big Bang, and several candidates have been discovered at $z\sim15-…
