Two  type  of    AGN  “modes”  

1)  Quasar  mode:      cold disk gas is  driven  onto  central  black  hole                                                                  (X-­‐Ray  emission)  

2)  Radio  mode:  sub-­‐Eddington  accreQon  from  hot gas Efficient  at  late  Qmes,  ongoing  heaQng  source  Mechanism  observed  in  central  part  of  clusters  (Bubbles)                                                  Radio  emission

If  there  is  AGN  Feedback  that  stop  the  star  formaQon,  there  should  be  a  clear  co-­‐evoluQon  between    AGN  and  normal  galaxies  

We  know  how  evolves  the  stellar  mass  funcQon    (Micol  talk),  but  AGN?  

DIFFICULTIES  

1)What  type  of  AGN  (Spectral,  X-­‐ray,  Radio  ……)  2)  Occurrence  (different  life  Qme  )  3)  Different  detectability

Conclusions

-­‐Non  passive  radio  AGN  and  type  2  x-­‐ray  AGN  occupy  same  Stellar  mass  range  and  environment        same  populaQon  

-­‐constat  flow  of  both  radio  non  passive  and  x-­‐ray  AGN  With  respect  the  general  populaQon  (i.e.  raQos  are  constant)  

-­‐New  passive  galaxies  have  almost  all  a  central  radio  AGN  And  become  ellipQcals  at  high  densiQes  but  with  lower  radio  power  with  respect  to  pre-­‐exisQng  AGN
