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…

A large, chemically enriched, neutral gas reservoir in a galaxy at z = 6.782

A. Saccardi, S. D. Vergani, L. Izzo +23

The chemical characterization of galaxies in the first billion years after the Big Bang is one of the central goals of current astrophysics. Optical/near-infrared spectroscopy of l…

Galaxy Formation and Symbiotic Evolution with the Inter-Galactic Medium in the Age of ELT-ANDES

Valentina D'Odorico, James S. Bolton, Lise Christensen +21

High-resolution absorption spectroscopy toward bright background sources has had a paramount role in understanding early galaxy formation, the evolution of the intergalactic medium…

The cosmic build-up of dust and metals. Accurate abundances from GRB-selected star-forming galaxies at

K. E. Heintz, A. De Cia, C. C. Thöne +38

The chemical enrichment of dust and metals in the interstellar medium (ISM) of galaxies throughout cosmic time is one of the key driving processes of galaxy evolution. Here we stud…

First stars signatures in high-z absorbers

Stefania Salvadori, Valentina D'Odorico, Andrea Saccardi +2

The first stars were likely more massive than those forming today and thus rapidly evolved, exploding as supernovae and enriching the surrounding gas with their chemical products.…

Evidence of First Stars-enriched Gas in High-redshift Absorbers

A. Saccardi, S. Salvadori, V. D'Odorico +6

The first stars were born from chemically pristine gas. They were likely massive, and thus they rapidly exploded as supernovae, enriching the surrounding gas with the first heavy e…

Dissecting the interstellar medium of a z=6.3 galaxy: X-shooter spectroscopy and HST imaging of the afterglow and environment of the Swift GRB 210905A

A. Saccardi, S. D. Vergani, A. De Cia +35

The study of the properties of galaxies in the first billion years after the Big Bang is one of the major topic of current astrophysics. Optical/near-infrared spectroscopy of the a…

The optically elusive, changing-look active nucleus in NGC 4156

Giulia Tozzi, Elisabeta Lusso, Lapo Casetti +21

We report on the changing-look nature of the active galactic nucleus (AGN) in the galaxy NGC 4156, as serendipitously discovered thanks to data acquired in 2019 at the Telescopio N…
