摘要：

Black hole formation is an inevitable consequence of relativistic core collapse following the gravothermal catastrophe in self-interacting dark matter (SIDM) halos. Very massive SIDM halos form supermassive black holes (SMBHs) greater than or similar to10(6)M. directly. Smaller halos believed to form by redshift z = 5 produce seed black holes of (10(2)-10(3))M. which can merge and/or accrete to reach the observational SMBH range. This scenario for SMBH formation requires no baryons, no prior star formation, and no other black hole seed mechanism.
