Cosmic Dawn Center
@cosmicdawncenter.bsky.social
The Cosmic Dawn Center (DAWN) DAWN is a collaboration between the Niels Bohr Institute (U. Cph) and DTU Space, dedicated to uncovering how the first galaxies, stars and black holes formed and evolved in the early Universe.
4MOST will observe the sky over the next 15 years, creating the largest spectroscopical atlas of the southerne hemisphere to date.
Several researchers at NBI and DAWN are involved in this project, including Johan Fynbo and affiliated assoc. prof. Jens-Kristian Krogager who lead a study on quasars.

The five main themes of the workshop are:
🌀 Galaxy formation at cosmic dawn,
🌀 Reionization,
🌀 Origin of massive galaxies and AGN,
🌀 Dust and chemical enrichment, and
🌀 Galaxy morphology and dynamics
in the era of JWST, ALMA, and Euclid.

The 150 spectra include
🌀 new deep spectroscopy of 10 key targets,
🌀 weak Hα+absorption features
🌀 2 AGNs out of 10 key targets
🌀 new Dn4000/UVJ insights
This is just the start — deep dives into stellar ages, dynamics, & more coming soon.
A public data release is also planned.

For instance, Shuntov et al. show how the galaxies' dark matter halos initially outpace galaxy assembly.
However, as accretion of gas and dark matter begins to slow down after some 1.5–2 billion years, halo growth stagnates while accumulated gas reservoirs keep star formation going.
