My invited lecture:
Difficulties of the QPOs Resonance Model

Detailed motivation for the travel

My invited talk at the Bombay colloquium will describe difficulties and problems with our resonance QPOs model. The model was developed by Wlodek Kluzniak and myself (in collaboration with several colleagues from Europe, USA, Mexico and Japan) to explain double peak, high frequency quasi-periodic oscillations (QPOs) in the observed X-ray fluxes from astrophysical black hole and neutron sources.

There is a general consensus among astrophysicists that understanding QPOs is of a fundamental importance to black hole and neutron star physics, and that QPOs provide the most practical way to study several aspects of super-strong gravity close to black holes and neutron stars. Many experts consider our resonance model to be the best model proposed to explain the QPOs phenomenon. Its acheivements are known and appreciated, and it is probably for this reason that I was invited to give a talk at this prestigeous international colloquium.

Our model is now mathematically sound and quite mature. It has, however, several profound problems and difficulties. We need to understand the nature of them in order to be able to make further progress. One obvious way is to discuss these problems with top experts, and for this reason I decided to accept the invitation to attend the colloquium in Bombay, as it would be attended by world's leading experts in the subject. I am convinced that this will be practically beneficial for my research.

Dear Marek,

We are arranging an International COSPAR Colloquium on "Spectra and Timing of Accreting X-ray Binaries" in Bombay, India on January 17-21, 2005, the venue being the Tata Institute of Fundamental Research (TIFR) in Bombay. I am the Chair of the Department of Astronomy & Astrophysics (DAA) at TIFR, and it is my great pleasure to invite you on behalf of COSPAR, TIFR, and DAA to give an invited talk at this colloquium on a topic of your choice.

Our International Science Organizing Committee consists of (in alphabetical order): P. C. Agrawal, P. Ghosh, G. Hasinger, E.P.J. van den Heuvel, W. Hermsen, S. S. Holt, M. van der Klis, S. Kulkarni, J.-P. Lasota, R. K. Manchanda, F. Mirabel, F. Nagase, J. P. Ostriker, A. Parmar, J. Poutanen, K. P. Singh, L. Stella, J. H. Swank, P. Ubertini, M. C. Weisskopf, N. E. White, and A.

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.
