Article Synopsis
- Massive galaxy clusters dating back to 3.9 billion years after the Big Bang contain stars formed even earlier, as predicted by cold dark matter cosmological models.
- Researchers discovered a protocluster from 1 billion years post-Big Bang (z = 5.3), which is over 13 megaparsecs wide and includes a bright quasar and abundant molecular gas.
- The observed massive galaxies in this region suggest there is at least 400 billion times the mass of our sun in dark and luminous matter, aligning with simulations for early galaxy clusters.
Lyman-alpha emitters are thought to be young, low-mass galaxies with ages of approximately 10(8) yr (refs 1, 2). An overdensity of them in one region of the sky (the SSA 22 field) traces out a filamentary structure in the early Universe at a redshift of z approximately 3.1 (equivalent to 15 per cent of the age of the Universe) and is believed to mark a forming protocluster.
