Overview

Cosmological simulations reveal fast-growing black holes in early galaxies, suggesting unique formation processes.

Key Points

  • This research aims to explore the formation and growth of the first massive black holes and their impact on galaxy evolution.
  • Implemented cosmological hydrodynamic simulations (SEEDZ)
  • Modeled Population III and Population II star formations
  • Analyzed black hole feedback and accretion mechanisms
  • Studied relationships between black hole and galaxy masses at high redshift
  • Black holes grow faster than their host galaxies, leading to over-massive black holes at high redshifts.
  • The observed black hole-galaxy mass relationship emerges in more mature galaxies.
  • Simulations predict MBH growth from heavy seeds up to significant masses, matching observed trends.
  • Continued simulations will compare against JWST observations for further validation.
