The Takeaway
This chemically primitive galaxy hosts a giant black hole that shouldn't have had time to grow that big in the early universe. It suggests that some black holes are born as "seeds" that are already massive, rather than growing slowly over billions of years.
From the abstract
JWST has revealed a large population of massive black holes (BHs) in the early Universe with unusual properties which mark them as distinct from low-redshift active galactic nuclei. Such findings have prompted the development of new models of BH formation and growth, and of their co-evolution with host galaxies. Linking the gas-phase metallicity of BH environments to seed masses is key to understanding which evolutionary pathways could explain the population of JWST-discovered BHs. We present ne
