A Cosmic Miracle: A Remarkably Luminous Galaxy at Confirmed with JWST

Rohan P. Naidu, Pascal A. Oesch, Gabriel Brammer +43

JWST has revealed a stunning population of bright galaxies at surprisingly early epochs, , where few such sources were expected. Here we present the most distant example of t…

On the origins of oxygen: ALMA and JWST characterise the multi-phase, metal-enriched, star-bursting medium within a 'normal' galaxy

Joris Witstok, Renske Smit, William M. Baker +29

The unexpectedly high abundance of galaxies at revealed by JWST has sparked a debate on the nature of early galaxies and the physical mechanisms regulating their formation…

Interstellar Ices as Carriers of Supernova Material to the Early Solar System

Martin Bizzarro, Martin Schiller, Jesper Holst +10

Planetary materials show systematic variations in their nucleosynthetic isotope compositions that resonate with orbital distance. The origin of this pattern remains debated, limiti…

Inefficient dust production in a massive, metal-rich galaxy at uncovered by JWST and ALMA

Kasper E. Heintz, Darach Watson, Francesco Valentino +17

Recent observations have revealed a remarkably rapid buildup of cosmic dust in the interstellar medium (ISM) of high redshift galaxies, with complex dust compositions and large abu…

Early galaxy evolution: The complex interstellar medium distribution of the z~7 galaxy A1689-zD1

Kirsten K. Knudsen, Darach Watson, Johan Richard +12

We observed the gravitationally lensed () galaxy A1689-zD1 at in bands 3, 6, and 8 of the Atacama Large Millimeter/submillimeter Array. These high-resolut…

Novel auroral line measurements extend the gradual offset of the FMR deep into the first Gyr of cosmic time

Clara L. Pollock, Rashmi Gottumukkala, Kasper E. Heintz +15

The mass assembly and chemical enrichment of the first galaxies provide key insights into their star-formation histories and the earliest stellar populations at cosmic dawn. Here w…
