Abstract

The formation, accretion and growth of supermassive black holes in the early universe are investigated. The accretion rate M is calculated using the Bondi accretion rate onto black holes. Starting with initial seed black holes with masses M_{\rm BH}∼ 10²-10³M_\odot, the Bondi accretion rate can evolve into a supermassive black hole with masses M_{\rm BH}∼ 10⁹-10¹⁰M_\odot and with a young quasar lifetime ∼ 10⁵-10⁶ years by super-Eddington accretion.
