Massive Black Holes from Dissipative Dark Matter

Understand

We show that a subdominant component of dissipative dark matter resembling the Standard Model can form many intermediate-mass black hole seeds during the first structure formation epoch.

• We also observe that, in the presence of this matter sector, the black holes will grow at a much faster rate with respect to the ordinary case.
• These facts can explain the observed abundance of supermassive black holes feeding high-redshift quasars.
• The scenario will have interesting observational consequences for dark substructures and gravitational wave production.
