OPEN QUESTIONS IN AGN RESEARCH

1.  Growth of Super Massive Black Holes (SMBHs)
        Due to mergers, accretion, stellar captures?
        Which most important?

2.  SMBHs and Galaxy/LSS formation:
        Were BHs seeds or by-products of galaxy formation?
         How important is the feedback from SMBH's in structure formation?
         What is the role of accreting BHs in the reionization of the Universe?

3.  Jets in AGN
         Are jets matter or Poynting flux dominated?
          Why are some quasars radio-loud and some radio-quiet?

4.  Accretion Physics:
          Is our basic cartoon of the central engine correct?
           Is the unified model viable?  useful?
           Have we included the essential physics?
          What role do outflows play?
