GoKawiilNew cosmological simulation traces black hole and 'little red dot' formation from dark matter halos
Researchers built a high-resolution dark-matter N-body simulation, seeded with Planck cosmological parameters, tracking halo mergers from redshift 35 to 7.5 using ROCKSTAR and CONSISTENT-TREES tools. They layered a semi-analytic galaxy-formation model onto this framework to simulate gas cooling, star formation, supernova feedback and radiation, showing that overmassive black holes and compact 'little red dot' galaxies emerge naturally from these early-universe conditions without requiring exotic physics.
