Waldek was interested in this subject during the 2002/2003 academic year. Any students interested in this theme, please edit this page a translate this to a page FormacjiGalAGN w po polsku.


  • FLRW model

  • unified AGN model

galaxy formation model

  • small density perturbations of about 10^{-5} at z=1100 grow with time
by gravitational collapse and form dark matter (baryonic + non-baryonic) haloes, which merge and become successively larger

  • gas cools and forms stars in the haloes



SMBH/AGN formation questions

  • Do any SMBHs start forming before DM haloes have formed?
  • Do SMBHs form in the "initial" collapse of a halo, or only when haloes and/or galaxies merge?
  • Do SMBHs "light up" as AGNs during major mergers of galaxies (mergers between two galaxies of similar mass) or also during minor
mergers (galaxies of different mass, e.g. ratio 10:1)?

intuition/education - nice g formation movies
