Formation of supermassive primordial black holes by Affleck-Dine mechanism

Understand

We study the supermassive black holes (SMBHs) observed in the galactic centers.

• Although the origin of SMBHs has not been well understood yet, previous studies suggest that seed black holes (BHs) with masses $10^{4-5}M_\odot$ exist at a high redshift ($z \sim 10$).
• We examine whether primordial black holes (PBHs) produced by inhomogeneous baryogenesis can explain those seed black holes.
• The inhomogeneous baryogenesis is realized in the modified Affleck-Dine mechanism.
