5 Chinese elements
q Culturally dependent: No Air - Wood & Metal instead q Different elements in AGNs?


Tori & Winds, Leicester 14 September 2004

Elvis 2000: pluses, minuses
q UV/X-ray connection
· FUSE, STIS partial covering, transverse; broader abs = edge-on [Kriss, Kaastra] · location: disk or torus [M.E., Kriss, Kaastra] · WA variability. Higher X-ray resolution at <1keV (R~5000), need spectra in ~hours.

q Funnel shape
· `Vertical' region no pro or con? reverberation red/blue symmetry · Radial region - Compton t~1 wind: ASTRO-E2
ё Spectropolarimetry: Ha PA, %polz'n [Axon, Kishimoto, Tadhunter]

q Phases, pressure Equilibrium/continuous?

[M.E., Kaastra, Collin].

· BELR in wind? NGC3227 abs'n event [McHardy]

q 0.1c winds: part of disk wind? Only Edd.limited? Photosphere
[Pounds, Reeves, Lawrence], UV blueshifts-smaller [O'Brien]
· ASTRO-E2

More Tests & challenges
q eigenvector 1 = mdot?
· · · · Wind moves out, gets stronger at high mdot? SCAR: BH masses too low? [Collin] Variability - FWHM(Hb) [McHardy] BAL quasars: radio-loudness vmax link - mdot?[Wills]

q large scale wind
· NLR bi-cones? Opening angles? Matter or radiation bounded? [OIII] aligned w. radio [Schmitt] · HI outflows: or radio jet cocoon? [Morganti, Beswick, Axon] · How many ways to make type 2 AGNs? [M.E.]

q Evolution:
· Obscured population, vs z. [Simpson] Just a phase black holes go through? · Star formation in disk [Nayakshin, Collin] · Star formation/AGN link. Black hole growth. SCUBA [Alexander] · Is a wind required for accretion to occur? [Fabian]

Black Hole Evolution
q Obscured population, vs z. [Simpson] Just a phase black holes go through? q Star formation in disk. BELR abudances [Nayakshin, Collin] q Star formation/AGN link. Black hole growth. SCUBA [Alexander] q Is a wind required for accretion to occur? All AGNs have BELRs & so wihds? [Fabian, M.E.]

Relativistic Fe-K Em. Lines
q q q q q Yes! [Fabian] 2rg No (mostly) [Reeves] 10rg (?) if present Yes, but... Schwartzchild [Done] 6rg Yes, in spikes [Turner] 6-20rg ... or wind [Turner]


Pharos:A GRB Afterglow Mission
Martin Elvis (CfA), F. Fiore, F. Nicastro., astro-ph/xxxxxx

·MIDEX class mission ·R>5000 X-ray Spectroscopy ·Out of plane gratings ·E< 0.87 keV only
·large area/mass ratio

·Rapid response ·GRB afterglows ·AGN monitoring
- > Warm Absorber location (from ionization, recombination) dynamics abundances partial covering

X-ray Polarimetry
q Diagnostic power for AGN & Quasar structure
· Where does the wind come from? · What is the scattering mechanism? · What is the geometry of AGN?

q Polarimetry is photon hungry
· 106 photons to measure 1% at 10s · THINK BIG

q MCP optics offer a solution
· square meters, yet MIDEX scale · Link with fundamental physics

q Extreme Physics Explorer
