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

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...

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...
