Studying primordial galaxies and black holes at cosmic dawn
Paper day! And it’s a big one 🥳

Today, a team of researchers led by @joriswitstok.bsky.social — A DAWN fellow @cosmicdawncenter.bsky.social and Post-doc in the PRIMORDIAL group — published a paper in @nature.com reporting the detection of Lyman-alpha emission from a galaxy at redshift 13 (!)

Witnessing the onset of reionization through Lyman-α emission at redshift 13 - Nature
Spectroscopy from the JWST Advanced Deep Extragalactic Survey of a galaxy at redshift 13 shows a singular, bright emission line identified as Lyman-α, suggesting the onset of reionization only 330 Myr...

The PRIMORDIAL team has two papers on ArXiv today! 🥳

The first one, led by Francesco Valentino, reports the detection of neutral gas outflows in two galaxies at z=4 and 7: arxiv.org/abs/2503.01990
Gas outflows in two recently quenched galaxies at z = 4 and 7
Outflows are a key element in the baryon cycle of galaxies, and their properties provide a fundamental test for our models of how star formation quenches in galaxies. Here we report the detection of o...

Ungt fysiktalent har set et mystisk lys fra en fjern galakse og har løst en kosmisk gåde
Lyset fra en fjern galakse har undret astrofysikere verden over. Nu har den 23-årige fysikstuderende Chamilla Terp løst den kosmiske gåde. To professorer er imponeret over hendes enkle måde at løse gåden på.
