Summary

Story summary

JWST discovered a protocluster of six galaxies at redshift 4.0, 12 billion years ago, forming 70–163 solar masses per year.
Aayush Saxena led a paper in the Open Journal of Astrophysics while Krisztina Gabányi authored a study in Astronomy and Astrophysics on the system.
EVN and e-MERLIN data showed jets, lobes and hotspots from a black hole, indicating the system is expected to become a brightest-cluster galaxy and reveal galaxy and black-hole growth.
