Description
Supermassive black holes (SMBHs), with masses exceeding 10^6
solar masses (Msun), are believed to reside at the centers of nearly
all galaxies and significantly influence their host galaxies through
the so-called "co-evolution" of galaxies and SMBHs. However, the
origin of SMBHs remains a mystery and a major challenge in modern
astronomy. In this talk, I will first review the current status of
cosmological simulations trying to reproduce the co-evolution of
galaxies and SMBHs. Then, I will present numerical studies that focus
on the formation of SMBHs with masses around 10^6 Msun, which are
considered the starting point of the subsequent growth toward heavier
SMBHs.
