Presentation Transcript

  1. Quasars and Galaxy Formation • By Joseph Silk and Martin J. Rees • 1997 • Presentation by Curtis McCully

  2. Outline • Star Formation vs. BH Formation • Early BH Formation • SMBH Results • Consequences

  3. Which Came First? • Stars or BH’s? • Generally assumed to be stars in 1997 • Let’s assume BH’s form first

  4. Formation and Early Growth of SMBH • Early BH: • Formation Efficiency:Where • Mergers

  5. SMBH Results

  6. Consequences • SMBH could eject all gas from the galaxy • BH Mass stabilizes from mergers

  7. SMBH and Galaxy Formation • Dwarf Galaxy formation suppression • High Star formation rates near SMBH • Star Formation stimulated by SMBH

  8. Conclusions • Self Regulation of BH growth • SMBH Stimulating galaxy formation
