Questions raised at the workshop
Throughout the week, the wide range of talks, posters, and
discussions raised a number of exciting and important outstanding
questions. We plan to address many of the key outsanding issues in the review
of the workshop to appear in New Astronomy Reviews.
from participants with regards to the questions below (or suggestions for additional issues to consider) would be very
valuable. If you would like to offer your perspective on any of these
issues, please send us an email at email@example.com, or
fill in the form below. Any and all contributions would be very much
Some key unresolved issues:
1. How can we link the various spatial scales (e.g., <1pc; 1-100pc;
1kpc)? Are the observations and models on those different scales
consistent? How well do we understand shock physics? What are the limitations in
the simulations? [session 1: "physics"]
2. How do quasars turn off? Do they stay off? Can we define evolutionary
tracks in the M-mdot plane? Many outbursts? Always Eddington limited? Is
radio loud a phase or different object population? Can we use X-ray
binaries to help address these questions or are there issues? [session 1: "physics"]
3. Why is the dark-matter halo mass of ~10^12-10^13 solar masses important
for the switching on of AGN/quasar activity? How much black-hole growth is
determined by halo mass? [session 2: "surveys"]
4. What is balance between merger and secular evolution? How can black holes
grow in satellite versus central galaxies? [session 2: "surveys"]
5. How important were "radio" and "quasar" modes at z~2 when the most massive
galaxies probably had their star-formation activity switched off? Down to
what radio powers is gas heating by radio jets important? What, if anything, can we
agree that we actually know about AGN feedback? Do we understand the physics of quasar versus radio mode feedback?
[sessions 2 and 4: "surveys" and "feedback"]
6. Can we uncover the seed-mass distribution? [session 3: "quasars"]
7. What can we believe in black-hole masses? How can we improve measurements?
Where is the evidence for black holes of 10^5 solar masses in galaxies?
[session 3: "quasars"]
