Supermassive black hole in the universe: the era of the HSC survey.

2012/12/20 : notes for discussion, which starts 10:50
  theoretical works 


***

 combine cosmological N-body simulaion with real universe by using SAM

 theoretical model construction, from galactic scale to accretin disk scale

 collaboration with HSC survey is very atractive studing "black hole" 
  for computation specialists
 ( dark matter simulation is not so attractive but)
  with K-computer 8000^3, 3x10^8M_sun simulation will be available on 2014.

***

 key parameters: 
 * mass suppy rate 
 * mass supply timescale
    
 problem: over-estimate number density of AGN (in SAM) 

***

 2 items theory can do
 * preparation of data analysis recipies
 * prediction of future observations

 Eddington ratio distribution;
  super-eddington accretion is more common at higher z. 
  search for high-z quasars, constrain BH growth mechanism

***

 how do you achieve super-eddington accretion ?
  direction of radiation is different from accretion rate  
  (not symetric radiation field)
  factor of a few super-eddington (10% of agn timescale)

  large purtabation is required for super-eddigton accretion
   Saitoh-san will investigate major merger driven accretion
  
  HSC observation provides wide range 
  (accretion rate, BH mass) information

***

 sophisticated theoretical prediction? SAM
  observations of clustering galaxies around quasars

  clarify what the data can tell us about the model/physics?
     
 AGN evolution model (with feedback, Kawakatsu model), 
  impossible to run whole parameter range
   needs good perspective for which range should be checked

***

 feedback from AGN outflow (large scale, kpc-scale)?
  radiative feedback drives outflow  
  hard to terminate star formation (low density, inhomogenity)   
   but jet can do even for cluster scale 

 how accurately estimate the eddington ratio?
  e.g., high-z quasars at high eddington ratio, biased?
