  4. Worst/best invention of the week • Worst: ETFE • Eddington-tuned feedback event • Best: • Jet-inhibited star formation • (I love it!)

  5. So, what’s new in the last decade? • BH and bulge masses — all new • Orientation-based unification— yes, sure, but… • Birth & evolution: • Reionization — BH or stars? • FRI/FRII - not resolved (see later) • RL/RQ - hidden parameter (see later) • Starburst - AGN - merger ?? • Gaseous environment: • Identification of emitting components • Big halos — what do they mean? • Do we understand the ‘alignment effect’? • Clustering properties of populations — lots new • Surveys — lots and lots new • The SKA resolution is (will be) critical

  6. Did anyone say you could leave?

  7. Sit down! That’s better.

  8. Blue herrings and cosmic bananas • The 1960’s were a really, really long time ago… • Phillip Best’s thesis, which was a really long time ago now… • I feel very, very confident that we have not even begun to address that issue yet… • …with our complete sample of one… • How would you classify Pictor A? • “Pictor A is in the South.” • Geoff Bicknell’s simulations are really cool… • These are “veery nice” results… • and they are all consistent with our preconceptions! • 6C quasars have a more snotty structure… • …it walks like a duck, it quacks like a duck, it’s a giant elliptical.

  9. Quotes of the week • In every NL object there is a BL object longing to get out • We call this the Clint Eastwood cloud: “Make my day; blow me away.” • Ha is “older and more settled” • Reconciling things with physics is often very nice. • …searching for extra-terrestrial intellegence in the US (Texas perhaps?)

  10. How do we assemble an evolutionary sequence? • Merger -> ULIRG -> RG -> E (3L*) -> cluster/field • Can we have a RG/RQ before a ULIRG? • What are the EROs and how do they fit into this scheme? Are the E-EROs and the dusty EROs part of the evolutionary sequence? • When and how often can they be a RG? • Does the factor 10–1.5 give the radio duty cycle? • What does metallicity tell us about ordering the sequence?

  11. How are FRI and FRII different? • How is the classification made? • Radio morphology • Radio power • Galaxy environment — clusters… • But what is the physics? • Evolution from one to the other? • … • Are the FRII’s at z~3 different beasts from those at z~0?

  12. What are the large gaseous halos? And the one in B20648+27 was THIS big! • How do we see them? • X-ray hot • Lyawarm • HI cool • CO cold • What part - if any - is primordial? • What part is metal enriched and how did it become so? • How do they evolve? • How can we use them - for mass determination etc.?

  13. So what is the difference between RQ and RL sources? • Is there a good definition of radio-loudness? • Is it bimodal? • What about the intermediate sources? • Is there a ‘hidden variable’ and what is it? • Accretion rate - no? • BH spin? • Can an ‘event’ change the state? • Merger -> spin-up/down
