Worst/best invention of the week
Worst: ETFE
Eddington-tuned feedback event
Best:
Jet-inhibited star formation
(I love it!)
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
Did
anyone
say you
could
leave?
Sit down! That’s better.
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.
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?)
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?
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?
What are the large gaseous
halos?
How do we see them?
X-ray
Lya
HI
CO
hot
warm
cool
cold
And the one in
B20648+27
was THIS big!
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.?
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
