Dear Prof. Abramowicz, Dear Marek,

may I remind you about our Conference "Growing Black Holes: Accretion in a
Cosmological Context", to be held in Garching next June, 21-25 (please
see the conference web-site at http://www.mpa-garching.mpg.de/~bh-grow/). 

It seems that till now we do not have any talk describing  possible models
of strongly super-Eddington luminosities in connection with the
subject of black holes growth. It is important also to discuss
theoretical models that allow strongly super-Eddington accretion and
only slightly super-Eddington luminosities. As you well know, 
the best models of this type were proposed by Polish scientists long
ago. Would you be able in a 20-25 minutes talk to describe the main
achievements of the models, including a discussion of the efficiency
of super-Eddington accretion as a function of the accretion rate?

Other relevant issues would be the following: Is it possible to get 
accretion rates 1000 times larger than the value corresponding to 
Eddington limit? How stable are these solutions? 

It would be great if you could mention the paper by J. Ostriker about
QSOs growth by capture of weakly interacting dark matter, and also remind 
people about solutions like the very old sketch I proposed with N. Shakura, 
where matter is outflowing and luminosity might grow as the logarithm 
of the accretion rate at the outer boundary (for your information, Andrew 
King will also be speaking about outflows from luminous Quasars at the 
conference). Obviously we should mention the latest results of Mitch 

Are you interested in such a talk? If yes, it will be included
into the list of key talks in the second circular, that we plan to
send out very soon, as a part of the session devoted to the issue: 
What sets QSO lifetimes and accretion efficiency? For your information, 
I attach the first circular, with a detailed list of topics to be 

Best Regards,

Rashid Sunyaev

I am Professor of Astrophysics (Chair) at Göteborg University and Chalmers University of Technology. In 1974 I earned my Ph.D. in theoretical physics from Warsaw University. After that I worked for several years at Stanford University and University of Texas at Austin. Later, for more than a decade, I collaborated closely with Dennis Sciama, first at Oxford University and then at the International School for Advanced Studies in Trieste. For twenty years I was a member of the Academic Board at the Salam's International Centre of Theoretical Physics in Trieste. In 1990-1994 I was professor of astrophysics at Nordita, the Nordic Institute for Theoretical Physics in Copenhagen. My interests include accretion discs theory, active galactic nuclei, neutron stars, black holes, nature of inertial forces and quantum effects in strong gravity. I supervised more than ten doctorates, and published more than 150 research articles.

6. A short description for the purpose of the conference

Topics to be discussed: Were black holes seeds or by-products of galaxy formation?; The growth of SMBHs due to mergers, accretion and stellar captures; How important is the feedback from supermassive black holes in structure formation?; What is the role of accreting black holes in the reionization of the Universe?; Sgr A* as a test-bed for our knowledge of the immediate AGN environment.; What does the X-ray Background tell us about AGN activity and obscuration, both at low and at high redshifts?; What sets QSOs lifetimes and their accretion efficiency? How is the SMBH activity connected to galaxy mergers and central star bursts?; What can we learn about AGN from studies of stellar mass binary black holes?; What is the connection between SMBH jets and accretion discs? Are jets matter or Poynting flux dominated?; SMBHs as sources of gravitational radiation.
