Cosmological simulations reveal how little red dots evolve into overmassive black holes
A new set of cosmological radiation-hydrodynamic simulations shows that heavy black hole seeds of about a million solar masses form naturally in dense protocluster regions, undergo a super-Eddington accretion phase that reproduces the spectral features of little red dots, and then grow into the overmassive black holes observed by the James Webb Space Telescope.
